Title:
CERAMIC COATING FILM FORMING AGENT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3475258
Kind Code:
B2
Abstract:
PURPOSE: To form a ceramic coating film having a low coefft. of thermal expan sion and excellent in heat resistance and electric insulating property on the surface of a metallic material at a lower temp. than the temp. at which an MgO coating film is formed by using a solid soln. of Mg-M3--O type binary oxide more excellent in reactivity than MgO as a coating film forming agent.
CONSTITUTION: Hydrotalcite compds. are fired to obtain the objective coating film forming agent contg. a solid soln. of Mg-M3--O type binary oxide represented by the formula as an effective component. The average secondary particle diameter of this coating film forming agent is regulated to ≤5μm, preferably ≤1μm and the BET specific surface area is regulated to about 30-200m2/g, preferably about 50-150m2/g because it is desirable that a coating film forming agent is less liable to flocculate and is satisfactorily dispersed in water, and CAA is regulated to for about 2-100min, preferably within a range of 0-60min.
