Beryllium copper

Beryllium copper, also known as beryllium bronze, is the "king of elasticity" of copper alloys. After solution aging heat treatment, products with high strength and conductivity can be obtained.The machinability, weldability and polishing properties of beryllium bronze are similar to those of common high copper alloys. 

Beryllium bronze can be divided into two categories. According to the composition of the alloy, beryllium content is 0.2%-0.6% for high conductivity (electrical and thermal) beryllium bronze, and beryllium content is 1.6%-2.0% for high strength beryllium bronze. According to the manufacturing process, it can be divided into cast beryllium bronze and deformed beryllium bronze. C is the most widely used beryllium bronze alloy in the world. Deformed beryllium bronze includes C17000, C17200 (high strength beryllium bronze) and C17500 (high conductivity beryllium bronze). The corresponding cast beryllium bronzes are C82000, C82200 (high conductivity cast beryllium copper) and C82400, C82500, C82600, C82800 (high strength wear resistant cast beryllium copper). The largest beryllium-copper alloy manufacturer in the world is Brush Wellman Company of the United States, whose enterprise standards correspond to international standards and have certain authority. The history of beryllium bronze production in China is almost synchronized with that in the former Soviet Union and the United States, but only high strength beryllium bronze QBe1.9, QBe2.0 and QBe1.7 are listed in the national standards. Other high-conductivity beryllium bronze or cast beryllium bronze have been put into mass production according to the needs of the development of petroleum industry and national defense industry.

Beryllium bronze has good comprehensive properties. Its mechanical properties, such as strength, hardness, wear resistance and fatigue resistance, rank first among copper alloys. Its electrical conductivity, thermal conductivity, non-magnetic, spark resistance and other properties can not be compared with other copper materials. The strength and electrical conductivity of beryllium bronze are at the lowest value in the solution soft state. After work hardening, the strength is improved, but the electrical conductivity is still the lowest value. After aging and heat treatment, the strength and conductivity of the alloy increase obviously.

Supply boron nitride for sell with factory price

Boron nitride is a heat and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN. It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic (sphalerite structure) variety analogous to diamond is called c-BN; it is softer than diamond, but its thermal and chemical stability is superior. The rare wurtzite BN modification is similar to lonsdaleite and may even be harder than the cubic form.

Nickel-copper alloys

Nickel-copper alloys are mostly used to make components, such as traveling wave tubes and magnetrons, which require high corrosion resistance, high temperature fatigue resistance and so on. Nickel-copper alloy is composed of 60% nickel, 33% copper and 6.5% iron. Nickel-copper alloy has good room temperature mechanical properties and high temperature strength, high corrosion resistance, good wear resistance, easy processing, non-magnetic, is a good structural material for manufacturing traveling wave tubes and other electronic tubes. It can also be used as structural material of aeroengine.

Adding copper to nickel will have a series of effects on various properties of nickel, especially corrosion resistance, mechanical properties and physical properties. Generally, the addition of copper improves the corrosion resistance of nickel in reducing medium, but decreases the corrosion resistance of nickel in oxidizing medium and the oxidation resistance in air. The addition of copper increases the strength, hardness and plasticity of nickel, and decreases the plasticity slightly. The addition of copper increases the thermal conductivity of nickel.

Cobalt carbonate

Cobalt carbonate is a red monoclinic crystalline or powder. Toxic, irritating eyes, respiratory system and skin.It is mainly used to produce cobalt chloride, cobalt sulfate, cobalt oxide, cobalt metal and cobalt naphthenate.As a raw material for manufacturing cobalt oxide, it is used for manufacturing cathode materials for lithium batteries.It is also used for making discolored pigments, glass pigments, ceramics, feed trace element additives and trace element fertilizers.

The ceramic industry is used as a colouring agent in the manufacture of cobalt salts and in the colouring of porcelain. Used as beneficiation agent in mining industry. Organic industry is used to manufacture catalysts, camouflage coatings and chemical temperature indicators. It is used as trace element fertilizer in agriculture. Used as analytical reagent in analytical chemistry.

At present, the existing calcining equipment includes: kiln tail, pouring body, supporting frame, kiln cylinder body and kiln head; the pouring body is arranged at both ends of the kiln cylinder body, and the kiln tail and kiln head are respectively fixed on the pouring body at both ends of the kiln cylinder body; the supporting frame is respectively provided on the kiln tail and kiln head; one end of the kiln cylinder body near the kiln tail is provided with a baffle, in addition. One end is provided with an anti-skid plate.

However, when calcining cobalt carbonate with existing calcining equipment, because cobalt carbonate is granular and powdery, it is easy to send and accumulate in the feed section of rotary kiln, which makes cobalt carbonate not completely calcined, or the calcining effect is poor, so that the calcined product cobalt oxide is not ideal.

Silicon (Si) - the second richest element in the earth's crust

Today's video focuses on a very common non-metallic element - silicon. It is a carbon group element in the third period of the periodic table.

In 1811, French chemists first obtained impure amorphous silicon by heating potassium and silicon tetrafluoride, which can be obtained in a variety of ways. In the crust, it is the second most abundant element, which makes up 26.4 percent of the total mass of the crust, is second only to oxygen.

Silicon, usually in the form of complex silicates or silica, is found in rocks, gravel and dust. Pure silicon has amorphous silicon and crystalline silicon allotropes. Gray, shiny crystalline silicon looks more like a metal than black amorphous silicon. Silicon is insoluble in water and ordinary inorganic acids, such as nitric, hydrochloric, and sulfuric; It's soluble in hydrofluoric acid and alkali solutions.

The simplest way to make silicon is to heat a mixture of silica sand and magnesium powder. Heating up a small portion of the tube containing the mixture, when the temperature reaches, you will see that the reaction will immediately begin, emitting high temperatures, white smoke and dazzling white light; In this phenomenon, two reactions occur simultaneously, silica and magnesium react to form magnesium silicide and amorphous silicon. In this reaction, magnesium reacts not only with sand, but also with glass tubes, which also contain silica. That's why the tubes are destroyed, not just because of the high temperatures. If you break the test tube, you can see the product; Dark brown dust is amorphous silicon. And when you pour this stuff into dilute hydrochloric acid, you will see something very interesting which is the magnesium silicide reacted from the previous reaction with hydrochloric acid. And it immediately reacts with oxygen, that's why we saw the spark. Silane and methane are formulated in a similar way, with silicon atoms instead of carbon atoms. Unlike methane, methane needs to ignite before it can react with oxygen to start burning while Silane can start burning with oxygen on its own.

Another interesting experiment is to make silica gel. When dilute hydrochloric acid is added to a solution of sodium silicate, commonly known as sodium silicate, a jelly-like gel is formed after a period of time. However, if you add concentrated hydrochloric acid, you won’t get a gel, and the resulting solution is in a sol state and can still flow. But when you heat the solution, it ends up as a silicone gel.

It's still sodium silicate, and if you add a little bit of ferric chloride, you can see the product grow like a living seaweed. Everyone can try it at home and see what your algae look like. You can also substitute calcium, magnesium, copper, nickel, cobalt, barium, zinc, chromium and manganese salts for ferric chloride.

Nowadays, silicon can be found everywhere in people's life. The main component of glass is silicate compound salt, and silicon is also found in cement. High purity monocrystalline silicon is an important semiconductor material, widely used in diodes, transistors, thyristors and various integrated circuits. The chips and cpus inside computers are made of silicon. High transparency glass fiber can be produced from pure silica, which is widely used in optical fiber communication.

Silicon is one of the essential trace elements in human body, which is necessary in the formation of connective tissue and cartilage. Silicon is also a component of collagen.
