Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 250–350 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 250–350 μm and a purity of 99.5+% is an advanced, high-performance material engineered for applications requiring exceptional hardness, high thermal stability, and excellent chemical resistance. With a Mohs hardness of 9.5 and thermal conductivity superior to many conventional materials, this coarse-grade SiC powder is ideal for high-temperature industrial processes and demanding mechanical environments.

Manufactured to meet the standards of modern ceramics, metallurgy, and composites, this material exhibits low thermal expansion, excellent wear resistance, and consistent performance under stress. It contains no heavy metals, toxins, or radioactive elements, making it suitable for safe handling and processing.

• SiC Content: 99%

• Free Carbon: 0.05%

• Aluminum (Al): 0.018%

• Iron (Fe): 0.057%

• Calcium (Ca): 0.050%

• Heating Power: 30.343 KJ/mol

• Hardness: 9.5 Mohs

• Density (at 288 K): 3.216 g/cm³

• Compressibility Coefficient: 0.21 × 10⁻⁶

• Thermal Expansion Coefficient (1173 K): 2.98 × 10⁻⁶ K⁻¹

Storage Condition:
Silicon Carbide micron powder should be vacuum-sealed and stored in a cool, dry room. It must be protected from exposure to air and mechanical stress to preserve its integrity and performance.
