Lithium Alumino Silicate
033-C is a lithium alumino silicate having a coefficient of thermal expansion of near zero. This product is typically used in refractories where the firing temperature is less than about 1800 deg F. It can also be used as a filler in electronic applications where it is necessary to match the expansion of several materials, such as a resin and a substrate. The product is close to 100% reacted so it is stable in most applications.
