Features
Grayish white alpha crystal powder. Because it has a diamond type three-dimensional lattice structure, it has high temperature thermal stability, thermal shock resistance, chemical stability and good electrical insulation and hardness. Silicon nitride melting point 1900℃Chemicalbook, relative density 3.44. It is still stable when heated in the air to 1450 ~ 1550℃. Soluble in hydrofluoric acid, insoluble in cold, hot water and dilute acid, for concentrated sulfuric acid and concentrated sodium hydroxide solution is also very slow.
