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.
Lithium ribbon metal for solid silver metal, molecular weight of 6.941, 180.5 ℃ melting point, boiling point 1342 ℃, the density of 0.534 g/cm3, molecular weight: 6.94. The characteristic of having the lowest density and the highest electrochemical equivalent in a metal.
Chloroauric acid is an orange-yellow crystal, easily deliquescent and soluble in water. Heat breaks down into gold. Chloroauric acid is the most common compound of gold. Chloroauric acid is widely used in analytical reagents and gold plating reagents.
Molybdenum disulfide, molybdenum, the main component of molybdenite. Black solid powder with metallic luster. Chemical formula MoS2, melting point 1185 ℃, the density of 4.80 g/cm3 (14 ℃), mohs hardness is 1.0 ~ 1.5.
