Abstract

PURPOSE: To obtain an excellent electrically insulating film having excellent resistance to high temperature on the surface of a metallic plate, by forming a base layer consisting of an alumina powder with water glass on the surface of the metallic plate, and forming a coating layer consisting of a granular crystal alumina on the base layer.
CONSTITUTION: A paste prepared by mixing an alumina powder with water glass is applied to the surface of a metallic plate 1 to form a base layer (2a) having a thickness of 0.5mm. A granular crystal alumina having a grain diameter of 80W100 mesh is uniformly sprinkled over the undried and still tacky base layer (2a) to form a coating layer (2b) of the alumina having a thickness of 0.5W1mm. The resultant layers are then predried at ordinary temperature for about 1hr and then calcined at about 850°C to give an electrically insulating film 2, consisting of the base layer (2a) and the alumina coating layer (2b) on the surface thereof, and resistant to high temperature.
