Boron nitride powder is white color, it is a crystal composed of nitrogen atoms and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen.
Aluminum powder, commonly referred to as "silver powder", is a silver metallic pigment. It is made by adding a small amount of powder to pure aluminum foil, crushing it into scaly powder, and then polishing it.
Micro-silica fume is also called silica fume or condensed silica fume. When ferroalloys are used for smelting ferrosilicon and industrial silicon (metal silicon), many highly volatile SiO2 and Si gases are produced in the mine thermoelectric furnace.
