SiC foam ceramic filter 200 x 200 x 22 mm, 10 ppi.
SiC foam ceramic filters are open-pored ceramic bodies made of SiC (silicon carbide). Foam ceramic filters have a foam-like structure whose pores are continuous. Their free cross-section is dependent on the pore size, which have approximately the same dimensions. They refer to one inch and are available in 10 PPI (pores per inch). Foam ceramic filters are suitable for filtering oxidic impurities in the liquid melt
