Abstract
A high alumina sintered body composed of a substrate consisting substantially of .alpha.-Al.sub.2 O.sub.3 and a surface layer of mullite precipitated in situ on the substrate. The sintered body is obtained by molding and sintering a composition comprising a main component containing at least 75% by weight, based on the total weight of the composition, of .alpha.-Al.sub.2 O.sub.3 and a predetermined amount of silica, a mullite mineralyzing agent and B.sub.2 O.sub.3. The sintered body has a combination of excellent thermal shock resistance and mechanical properties such as flexural strength.
