Silicon nitride, which belongs to covalent bonding compounds, is an inorganic compound with the chemical formula Si3N4. It has excellent thermal stability, thermal shock resistance, chemical stability, good electrical insulation and hardness, and is an important structural ceramic material. It is generally divided into two crystal orientations, α and β, both composed of [SiN4] 4 tetrahedra. Among them, β - Si3N4 has higher symmetry and is a thermodynamically stable phase, while α - Si3N4 is more easily generated kinetically. ‌
