Abstract
A magnesia-based sintered body of a homogeneous composition having a porosity lower than 1% and a hydrateability lower than 0.3%, said sintered body having a chemical composition comprising 70 to 99.9% by weight of magnesia and 30 to 0.1% by weight of at least one oxide selected from the group consisting of titanium oxide, aluminum oxide, ferric oxide, phosphorus pentoxide, yttrium oxide, barium oxide, boron oxide, calcium oxide and lithium oxide. The sintered body is obtained by molding a powdery mixture of magnesia and the oxide other than magnesia.
