CERAMIC SINTERED BODY AND PRODUCTION METHOD THEREFOR, AND MEMBER MADE OF SAID CERAMIC SINTERED BODY
PROBLEM TO BE SOLVED: To reduce the electrical resistivity of a ceramic sintered body with alumina (AlO) as the parent phase without adding a large amount of conductive material.SOLUTION: Provided is a ceramic sintered body in which a conductive phase composed of InOor a conductive phase composed of a solid solution or composite oxide of InOand SnOis present in the parent phase composed of AlO, in which the amount of the conductive phase is 1 to 5 mol%, and the conductive phase is present in a planar or linear state between crystal grain boundaries of the parent phase.SELECTED DRAWING: Figure 2B
【課題】アルミナ（Ａｌ２Ｏ３）を母相とするセラミックス焼結体の電気抵抗率を、導電性物質を多量に添加することなく低下させる【解決手段】Ａｌ２Ｏ３からなる母相中に、Ｉｎ２Ｏ３からなる導電相、又はＩｎ２Ｏ３及びＳｎＯ２の固溶体若しくは複合酸化物からなる導電相が存在するセラミックス焼結体において、前記導電相の量は１〜５ｍｏｌ％であり、前記導電相は、前記母相の結晶粒界間に面状又は線状に存在している。【選択図】図２Ｂ
