Properties of Si3N4
2.1 Physical properties of Si3N4
State: Solid
Color: Green to black
Odor: Odorless
2.2 Chemical properties of Si3N4: Silicon Nitride is insoluble in water and most organic solvents. -
Silicon Nitride typically does not participate in common chemical reactions such as reactions with metals, acids, non-metals, or salts. It is particularly heat-resistant and does not undergo oxidation reactions until very high temperatures (> 1300°C).
