Nickel powder is also divided into carbonyl nickel powder, which is gray irregular powder and easy to oxidize in moist air. It is mainly used for coating and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference, for various high gloss decorative paints and plastics, instead of aluminium powder as anticorrosive paint in water system, etc. Fine spherical nickel powder can be used for conductive ink.

The molecule formula of nickel carbonate is NiCO3, and its properties are oblique light green crystals, which are decomposed above 300 C. Soluble in ammonia and dilute acid. It is insoluble in water. It is soluble in pure water containing CO2, soluble in ammonia water and dilute acid, insoluble in cold concentrated hydrochloric acid and nitric acid. When heated in the air, oxides are formed. The reaction with ammonium chloride solution yields CO2 and NH3, leaving nickel chloride (II) solution.
Nickel-coated graphite powder, also known as nickel-coated graphite powder, is a new kind of graphite strengthening material, which is obtained by electroless plating or vapor deposition of graphite powder.
Nickel-coated graphite powder can distinguish two kinds of properties. The first kind of powder used for thermal spraying has a coarse particle size and a gray appearance. The second kind of additive powder has fine particle size and dark gray or black appearance.
High purity Niobium pentoxide (Nb2O5) is a white powder. It turns yellow when heated and turns white when it cools. The temperature of 1460 ° C. If it is doped with impurities (such as magnesium oxide, lead oxide, etc.), it will change color after sintering at high temperature.
Nano-calcium carbonate is a new ultra-fine solid powder material developed in the 1980s with a particle size of between 0.01 and 0.1 μm. Due to the ultrafine refinement of Nano-calcium carbonate particles, the crystal structure and surface electronic structure change, resulting in quantum size effects, small size effects, surface effects and macroscopic quantum effects that ordinary calcium carbonate does not have.
Tourmaline powder is a powder obtained by mechanically pulverizing the tourmaline ore after removing impurities. The processed and purified tourmaline powder has a high negative ion generation amount and a far infrared emission rate.
Nano anion powder is made from natural materials through nanotechnology. Scientific research shows that nano-nano-ion powder can greatly help the human body to maintain energy and improve the living environment of human beings.
The mechanism of ionization of gas molecules in the air mainly depends on the effect of external urging on gas, and the catalyzed by ultraviolet light, radiation, photoelectric effect and the like.
Hexacarbonyl molybdenum is a coordination compound belonging to a metal carbonyl complex with the chemical formula Mo(CO)6. It is a white solid like the carbonyl compound of the same family, such as chromium hexacarbonyl or tungsten hexacarbonyl. It is volatile and stable in air, and the molybdenum atom is zero.
Nano-sized NH4-ZSM-5 zeolites with a wide SiO2/Al2O3 ratio range were directly synthesized through seed-induced approach. The crystal sizes could be controlled by simply adjusting the seeding gel amount.
Silicon dioxide nanoparticles, also known as silica nanoparticles or nanosilica, are the basis for a great deal of biomedical research due to their stability, low toxicity and ability to be functionalized with a range of molecules and polymers.
