Title:
MAGNESIA SPINEL REFRACTORY AND ITS PRODUCING METHOD
Document Type and Number:
Japanese Patent JP2004217488
Kind Code:
A
Abstract:
To provide a magnesia spinel refractory which has a coefficient of thermal expansion nearly equal to that of YSZ, a low air permeability, and excellent mechanical strength, and which is almost free from the formation of cracks and suitable for supporting members used in an SOFC using the YSZ as a solid electrolyte; and to provide a method for manufacturing the same.
The magnesia spinel refractory contains, by mass, 35-74% MgO component, 25-60% Al2O3 component, and 1-10% CaO component and is characterized in that the total content of MgO and Al2O3 components is ≥85 mass %, and it does not substantially contain SiO2 component.
