Abstract
A non-conductive ceramic material contains a base ceramic material and at least one other ceramic material having a lower coefficient of thermal expansion than that of the base material so that the coefficient of thermal expansion of the non-conductive ceramic material is identical to that of a metallic material to which it will be matched. Methods of making and using same are disclosed.
