Arsenic-copper alloy is a brown-red ingot-like Babbitt alloy, a bearing material, and the only material suitable for low hardness shaft rotation. Compared with other alloys, it has better adaptability and indentation. Because of its good wear resistance, casting, rubbing-in and chemical stability, it is widely used in ship machinery, hydroelectric machinery, cement machinery, paper machinery and mineral industry.
In the preparation of zirconium hydride powder, it is easy to be affected by the following factors which affect the quality of zirconium hydride powder.
Metal cobalt powder: The appearance is gray, and the particle shape is spherical or irregular, which depends on the smelting process. It is mainly used in powder metallurgy, thermal spraying and so on.
Tourmaline powder is mainly composed of tourmaline powder, ultrafine tourmaline powder and nanometer tourmaline powder according to its use and particle size. Applicable industries include: environmental protection, cigarettes, coatings, textiles, cosmetics, water purification, air purification, electromagnetic radiation protection, health care products, etc.
Yttrium, chemical symbol Y. It is the first rare earth metal element to be discovered. It is a grey ferrous metal with ductility. It reacts with hot water and is soluble in dilute acid. Special glass and alloy can be made.
Nano grade anion powder is elaborately made from natural materials through nanotechnology. Scientific research shows that nano-anion powder is of great help to keep energetic and improve human living environment.
The main uses of nano-anion powder are as follows:
Hydroxylation and hydroxylation graphene belong to functional graphene.Generally, graphite and alkali metal solids are milled continuously in a high energy ball mill, and graphene dispersed in water is treated with low frequency and high voltage pulse current. Hydroxyl-only water-soluble graphene can be obtained.
Vanadium is a malleable metal, but vanadium containing oxygen, nitrogen or hydrogen is brittle. Vanadium is a poor conductor of electricity and its conductivity is only one-tenth that of copper. At room temperature, fine vanadium is stable to oxygen, nitrogen and hydrogen. When heated in air, vanadium is oxidized to brown-black, blue-black vanadium tetroxide, or orange-red vanadium pentoxide. Under low temperature (180 ℃), the effect of vanadium and chlorine. Vanadium carbide and vanadium nitride were formed with carbon and nitrogen at high temperature.
The platinum powder with micron size is spherical and polygonal. Shaking density 1.0 ~ 4.0g/cm3. Average particle size 1.1 ~ 1.7 m. The specific surface area is 5 ~ 15m2/g. Chloroplatinic acid solution was obtained by dissolving sponge platinum in aqua regia, adjusting acidity, adding dispersant, heating and stirring, adding reductant (hydrazine hydrate, etc.), static cooling, washing and drying. 0.5 m ultrafine platinum powder.
FeSiAl alloy powder is a kind of deoxidizer used in steelmaking, which can improve the form of inclusions and reduce the content of gas elements in molten steel.
