PURPOSE:To obtain deuseness and high strength by compounding a specific ratio of spinel, by which shrinkage is suppressed without generating a liquid phase. CONSTITUTION:The magesia spinel of 0.1 to 1wt.% compounded to the zirconia partially stabilized by magnesia or calcia having prescribed grain size constitution is solutionized with the zirconia and sintering progresses without forming a liquid phase in the temp. region to be used, by which the dense body is obtd. |
