This silicon carbide (SiC) micron powder from Nanografi has a stated purity of 99+% and a particle size range of 16-49 μm. It is a very hard material, rated 9.5 Mohs, with a density of 3.216 g/cm3 at 288k. That combination suits it to refractory, ceramic and abrasive work.
The impurity profile is specified: free carbon at 0,05 %, Al at 0.018%, Fe at 0.057% and Ca at 0.050%. Silicon carbide also offers high thermal conductivity, and its thermal expansion coefficient is 2.98x10-6 at 1173k. These properties support parts that must keep their shape and strength at high temperature.
According to the manufacturer, the powder is not a radioactive mineral. It contains no heavy metals and no toxic or carcinogenic substances. It is supplied in 25 grams, 100 grams, 500 grams, 1000 grams and 5 kg packs.
- Hard, high-grade refractory material.
- Ceramics such as ceramic bearings, textile ceramics, high frequency ceramics and ceramic engine parts.
- Polishing abrasives and grinding wheels, as well as hard discs and supports for multichip modules.
- High temperature sealing valves, spray nozzles and fluid transport parts.
- Filler in composites to raise strength and heat resistance.
