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 powder of calcium carbonate

Submitted by admin on Wed, 05/22/2019 - 01:44

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.

Nano grade anion powder
