CERAMIC SPHERE, AND METHOD OF PRODUCING CERAMIC SPHERE
To provide a ceramic sphere whereon wear caused by applying external stress is suppressed.SOLUTION: The ceramic sphere contains zirconia in a ratio of 50 to 73 mol%, ceria in a ratio of 7 to 12 mol% and alumina in a ratio of 20 to 30 mol% and has surface roughness Sa of 60 to 400 nm, with the ratio of monoclinic crystal in the crystal structure determined by powder X-ray diffraction being 1 volume% or less.SELECTED DRAWING: None
【課題】外部応力の印加による摩耗を抑制したセラミックス球形体を提供すること。【解決手段】ジルコニアを５０～７３ｍｏｌ％、セリアを７～１２ｍｏｌ％、アルミナを２０～３０ｍｏｌ％含有し、表面粗さＳａが６０～４００ｎｍであり、粉末Ｘ線回折により求められる結晶構造の内訳に占める単斜晶の割合が１容量％以下であるセラミックス球形体。【選択図】なし
