High-Purity Silicon Carbide (SiC) Powder 99.9999% (6N) HPSI Type 100μm Particle Size SIC Crystal Growth
Silicon carbide powder (SiC), as a core material for third-generation semiconductors, exhibits high thermal conductivity (490 W/m·K), extreme hardness (Mohs 9.5), and wide bandgap (3.2 eV). It is primarily used for SiC crystal growth, power device substrate preparation, and high-temperature ceramic sintering. With ultra-high purity synthesis (≥99.9999%) and precise particle size control (50 nm–200 μm), it meets the requirements of PVT crystal growth furnaces and CVD epitaxial equipment.
Features
