Tech Ceramic has a long story and rich experience dealing with ceramic powders, utilizing high purity and fine powders with advanced technology, ceramic foam filters produced by TechCeramic have high porosity, homogeneous foam structure and good thermal conductivity, both for stability and resistence to sudden tempereature changes.

Ceramic foam filters have excellent filtering functions of screening, filtering, residuum collection and adsorption in molten metal liquid. It has good chemical stability and does not react with alloy liquid, effectively remove the oxides and non metal particles in the metal liquid to improve the purity of molten metal.
