COMPOSITION FOR MANUFACTURING CERAMIC MATERIALS

摘要

FIELD: manufacture of linings for heat resistant units and supports for firing ceramic products when high heat resistance is required. SUBSTANCE: claimed composition comprises (wt %): 56-70 alpha-form alumina 56 and the refractory clay balance. Properties of the resulting material are as follows: porosity 25-45%, shrinkage 1-4%, bending strength 20-40 MPa thermal resistance of more than 100 thermal cyclings at 1000 C (water). EFFECT: improved heat resistance of the manufactured product. 1 exi
