Low thermal expansion insulating ceramics Adceram-CS^®

Adceram-CS^®, low thermal expansion and heat-insulating ceramics

Adceram-CS^® is light weight and has unique thermal characteristics (a low coefficient of thermal expansion, low heat conductivity and high thermal shock resistance). Also, due to excellent heat insulation with small dimensional changes from heat, Adceram-CS^® can cope with abrupt temperature changes.
