Transformation toughened ceramic alloys

摘要

This invention is primarily directed to the production of transformation toughened ZrO₂-containing ceramic alloys wherein the toughening agent is selected from the group consisting of a rare earth metal vanadate and a magnesium and/or calcium tungstate/molybdate, and SnO₂ can be uti­lized as a toughening agent and/or a stabilizing agent for ZrO₂.
