Cerasil
Ceramic is an alumino silicate ceramic with properties similar to steatite, but with some distinct advantages. 223U has a lower thermal coefficient of expansion than steatite or high alumina ceramics which results in excellent thermal shock resistance.
223U also features lower firing temperature, consistent lower shrinkage and less tool wear resulting in lower cost and faster delivery. Cerasil 223U is ideal for volume production of small pressed insulators often replacing steatite or alumina parts.
