23/12/2017· 2,092. Dec 22, 2017. #1. We''ve had a few folks in threads recently mention dangers of inhaling diamond particulate, especially when using them dry. I think there is also some risk of working with silicon carbide. The key dangers being skin contact with a probable carcinogen, or inhalation of crystalline silica that could damage your lungs.

Silicon carbide is highly resistant to neutron radiation, devices based on it have a short response time, and it itself is durable and resistant to destruction by high-energy radioactive particles. The authors of Reference [ 2 ] showed that the absence of polarization effects under neutron and alpha irradiation makes silicon carbide an alternative to diamond sensors for detecting of fast neutrons.
23/12/2017· IDENTIFIION Silicon Carbide is a crystalline (sand-like) material which varies in color from clear to pale yellow or from green to black. It is used in pencils, sandpaper, ceramics, and abrasive grinding wheels, and as refractory material.
This card does not apply to silicon carbide in "fibrous" or "whisker" form. There is evidence of fibrosis in mixed dust situations, the risk of which is enhanced in persons with tuberculosis. There is no evidence that silicon carbide (non-fibrous) causes fibrosis in the absence of other dusts.
