Abstract (en)
[origin: WO9510640A1] A process for producing an oxide ceramic coating from a sol comprising a solution of a metallic compound, which aims at solving problems involved in various processes for producing an oxide ceramic coating, such as the vapor-phase methods including the chemical and physical vapor deposition methods which are generally low in productivity and the sol-gel method which, too, is low in productivity because only a thin coating of 0.1-0.3 mu m in thickness is formed in one coating run and in which a thick coating, evenwhen formed, is apt to crack because gel shrinkage occurs in evaporating off the alcohol component from the sol. The invention process permits production of a noncracking uniform oxide ceramic coating by electrostatically atomizing a sol comprising a solution of a metallic or silicon compound to form a gel coating scarcely containing solvent molecules on the surface of a substrate, followed by firing.
