Abstract
A dielectric ceramic substrate is obtained exclusively from aluminum oxide, magnesium oxide and titanium oxide, the respective amounts of said magnesium oxide and said titanium oxide being so selected as to represent substantially equivalent molar proportions. The novel substrate is adapted to be used in electronics in the fields of thin layer and thick layer technology, as well for producing microprocessor protection cases, multilayer substrates and the like.
