Ceramics Industry Overview

b sections covered
Sub-sectors covered
 Refractories
 Advanced / engineering ceramics
 Building Products



Diverse applications within one industry leading to
equally diverse requirements in some cases.
Some areas thermal measurements vital, other
areas very little requirement.
