Material Notes:
The SUPERSiC Material System allows customization of basic silicon carbide. Select from groups of infiltration materials, cleaning options, coating materials and thicknesses to optimize material for specific applications.POCO’s unique conversion process produces the highest quality silicon carbide products available on the market today. This process starts with graphite material specially designed and manufactured for use as the precursor in the conversion process. Near net parts are machined in graphite, purified, and subjected to a proprietary conversion process which substitutes pure silicon atoms for carbon atoms. The result is SUPERSIC, POCO’s high purity silicon carbide.
