ABSTRACT:
Sinterable raw material product for ceramics based on aluminum titanate, consisting essentially of particles having a core/shell structure with a core of an oxide, oxide hydrate or hydroxide of ether of aluminum or titanium on which are precipitated, as a shell, sparingly soluble compounds of the other aluminum or titanium not used as the core matrial, with the molar ratio of titanium to aluminum of from 1:0.1 to 1:30, which in addition to the precipitated compounds of aluminum or titanium contains additional sparingly soluble compounds of elements in a quantity of from 0.1 to 65% by weight, calculated as oxide of the element and based on the total quantity are useful in fabricating sintered bodies for high temperature environments which include internal combustion engine parts, tubes for transporting liquid metals, catalysts carriers and so forth.
