Title:
ELECTRICALLY CONDUCTIVE SINTERED CERAMIC AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH07196367
Kind Code:
A
Abstract:
PURPOSE: To obtain an electrically conductive sintered ceramic having uniform gas permeation, lowered overvoltage and high strength by constituting the sintered product with particles having a specific composition and particles sizes in a certain range.
CONSTITUTION: Ceramic powder mainly composed of La1-xSrxMnO3 (0.05≤x ≤0.5) and of 10 to 30μm average particle size is formed in a usual manner and fired to give the electrically conductive sintered ceramic of 10 to 50μm average particle size. It is also preferred that the main constitution is changed to (La1-x-Srx)a Mn1-y-zAlyNizO3 (0.8≤1≤1.0; 0.05≤x≤0.50; 0.01≤y≤0.03; 0.03≤z≤0.15) instead of La1-xSrxMnO3.
