ABSTRACT:
Mismatched expansions of monoclinic celsian and zirconia crystals and the refractoriness of both phases in a sintered ceramic body result in highly refractory, microcracked and thermal shock resistant products. Avoidance of the higher expansion hexagonal form of celsian is desirable to obtain the better thermal shock resistance.
