Abstract
An inorganic silicate cement composition has its thermal expansion coefficient controlled for use with different substrates subjected to temperature variations through the inclusion of selected inorganic filler materials. Selected metallic powder filler materials are provided to yield a relatively high thermal expansion coefficient and fused silica powder is provided as a filler material to yield a relatively low thermal expansion coefficient.
