Cordierite Insulator& Cordierite Ceramic& Cordierite
Cordierite ceramic is a type of magnesium aluminum silicate with particularly good thermal shock properties. Cordierite also has low thermal conductivity and thermal expansion, while also being cost-effective. Often used as a structural ceramic for kiln furniture applications, it also finds uses in other applications where rapid temperature changes take place.
Cordierite is a ceramic used in heat shock applications that would crack and shatter most other ceramic materials.
Kiln furniture is made of cordierite because it will survive thousands of heating and cooling cycles.
At Paratech all of our production is placed in cordierite trays known as saggers to be used in the kiln during the firing cycle.
Small cordierite parts can be dry powder pressed. Large cordierite pieces are formed by slip casting.
Slip casting is a process where the ceramic material is mixed with water and poured into a plaster mold. After a few hours the plaster draws off the water from the mix and the sagger or other shape can be released from the mold. Parts are then dried and fired.
