Abstract
A method of sintering green ceramic bodies comprised of polycrystalline bi- or multi-metal oxides comprising: (A) encapsulating the body to be sintered in a chamber having (i) an inner wall portion comprised of a sintered polycrystalline bi- or multi-metal oxide composition of the same type as the body being sintered such that upon heating during the sintering process volatile metal oxide constituents of said composition create an atmosphere of said constituents which surrounds the body being sintered and (ii) an outer wall portion comprised of a substantially impervious sintered ceramic which is essentially nonreactive with said polycrystalline bi- or multi-metal oxides; and (B) heating the chamber with said body encapsulated therein to a temperature and for a time necessary to sinter said body to the desired density.
