Abstract

PURPOSE: To provide the title substrate with good surface smoothness, good electrical charcteristics, improved heat and acid resistances for electronic parts by covering a SiO2-Al203-CaO-alkali metal oxide type glass film of a specified compsn. on an insulating ceramics substrate.
CONSTITUTION: A glass film consisting of, by wt., SiO2 70W85%, Al2O3 7W17%, CaO 0.5W5% and one or more kinds of alkali metal oxides 5W15% is formed on an insulating ceramics substrate by a usual method. A glass thin film formed on a conventional glazed ceramics substrate has a softening point of about 600W800°C, and the highest service temp. is about 700°C in practical use. The glass film of this invention withstands heat of temps. as high as 950W1050°C, and the acid resistance is 20W50% higher than that of the conventional film with respect to solubility in a mixed soln. of hydrofluoric acid/nitric acid=1/1.
