Gjenstand av keramisk materiale, samt fremgangsmåte for fremstilling av en slik gjenstand

摘要

A process for the production of a shaped article of a ceramic material in which a composition comprising particulate ceramic material and a liquid medium is shaped, the liquid medium is removed from the shaped composition, and the composition is heated to sinter the particles of ceramic material in which the composition is subjected to high shear mixing such that in the shaped article which is produced the mean maximum size of flaw is less than 25 microns. Also, a shaped article of sintered particulate ceramic material in which the mean maximum size of flaw is less than 25 microns and in which the minimum dimension of the shaped article is in excess of 0.1 mm.
