This silicon carbide (SiC) micron powder from Nanografi has a stated purity of 99.5+% and a particle size range of 28-70 μm. It is a very hard material, rated at 9.5 Mohs, with a density of 3.216 g/cm3 at 288k. It is intended for refractory, ceramic, abrasive and composite work.
The listed composition gives SiC at 99 %, with free carbon at 0,05 % and low levels of Al (0.018%), Fe (0.057%) and Ca (0.050%). Silicon carbide also has high thermal conductivity, so the powder suits parts that face high temperatures, such as sealing valves, spray nozzles and components that carry hot fluids.
Mixed into composites, the powder raises both strength and heat resistance. According to the manufacturer, the material is not radioactive and contains no heavy metals, toxic substances or carcinogenic substances.
- Hard, high-grade refractory material.
- Ceramic components such as ceramic bearings, textile ceramics, high-frequency ceramics and ceramic engine parts.
- Polishing abrasives, grinding wheels and hard discs.
- Support material for multichip modules.
- High-temperature sealing valves, spray nozzles and fluid transport parts.
- Composite filler to increase strength and heat resistance.
