CERASIC Atmospheric Pressure Sintered SiC (Heat-resistant Structural Products)

Heat-resistant Structural Products

CERASIC, a silicon carbide material sintered under atmospheric pressure, is a ceramic material that has superior properties in terms of machining, abrasion, and corrosion-resistance to corrosive gas and chemicals. It is widely used in heat-treatment, and its long life property makes it a recognized contributor to low running costs and the reduction of industrial waste.
In addition, CoorsTek can make large-scale products of 1000mm or more that is the largest size in the world as ceramic materials. (Plates: 1000X1000mm or more, Tubes: 2000mm or more in length)
