Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 5–20 μm

Product Description:
This high-purity Silicon Carbide (SiC) Micron Powder features a particle size range of 5–20 μm and a purity exceeding 99.5%, making it an excellent choice for advanced ceramics, thermal systems, and precision abrasives. Thanks to its ultra-hard nature (Mohs 9.5), chemical inertness, and thermal stability, this powder delivers outstanding mechanical and thermal performance even in aggressive environments.

Engineered for uniform particle distribution, this grade of SiC powder enables superior packing density and flowability in composite and sintering formulations. It is ideal for applications requiring fine particle integration into high-temperature or wear-resistant components.

Technical Properties:

• SiC: 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 (288K): 3.216 g/cm³

• Compressibility Coefficient: 0.21 × 10⁻⁶

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

Storage Condition:
To maintain stability, Silicon Carbide Micron Powder should be vacuum-sealed and stored in a cool, dry area, away from air exposure or mechanical stress.

Applications:

• Refractory linings and crucibles

• High-performance ceramic parts (e.g., bearings, seals, nozzles)

• Grinding wheels, lapping compounds, and polishing agents

• Abrasive coatings and composite fillers

• Thermal interface materials and heat-resistant components

• Support substrates for microelectronic modules and power devices

This material is non-radioactive, does not contain toxic elements or heavy metals, and is free from carcinogens, making it a safe and sustainable solution across multiple industries.
