Process for producing silicon carbide platelets - Alcan …
1993/11/2· However, silicon carbide whiskers are suspected of being a health hazard because, like asbestos fibres, they easily become airborne and can be ingested by humans or animals. There is therefore a need for an alternative to silicon carbide whiskers that offers similar reinforcing effects without the associated risks.
Union Carbide | Asbestos Exposure & Cancer Risks
Graphite can also be made from silicon carbide by heating it to about 4,500 degrees, which evaporates the silicon and leaves pure graphite. The furnaces used for graphite production at Union Carbide Niagara Falls were insulated on the inside with asbestos-containing refractory and on the outside with asbestos insulation.
