Product Description
High Purity Silicon Nitride Powder Si3N4 Price CAS 12033-89-5 for Fine Ceramic
Silicon Nitride (Si₃N₄) is a high-performance white to gray crystalline powder with a melting point of 1900 °C and a density of 2.2–3.5 g/cm³. It exists in two crystalline forms: α-Si₃N₄ (hexagonal structure) and β-Si₃N₄ (crystalline structure). The material exhibits exceptional hardness, high-temperature stability, and resistance to oxidation, making it one of the most important structural ceramics available today.
Silicon Nitride (Si3N4) powder is a high-performance engineering ceramic material widely used in advanced structural and functional applications. It is known for its excellent mechanical strength, thermal stability, and wear resistance.
