ABSTRACT:
A composition of ceramic material, useful for forming seals in apparatus intended to be subjected to high temperatures, for example electrical heating elements, includes kaolin, silica, and zircon, and also calcium, sodium and boron ions, e.g. as frit and borate components, whereby the material remains substantially free of bubbling or foaming during a stage of heating to expand and harden it, and has enhanced properties of impact resistance and resilience.
