摘要： A method of producing a glazed ceramic substrate, which is useful for a hybrid integrated circuit or a thermal head of a thermal printer for instance, by applying a glass onto a major surface of a ceramic substrate, firing the substrate to form a molten glass layer on the substrate surface and cooling the fired substrate. To obtain the glazed ceramic substrate with high flatness despite the tendency of the substrate to warp due to difference in thermal expansion coefficient between the ceramic and the glass, a refractory base which supports the substrate during the firing and cooling steps is so shaped as to allow the substrate to deform during the firing step reversely to the expected warp at the cooling step, so that the warp at the cooling step is offset by the preceding deformation. For example, the upper surface of the base is shaped into a continuous and concave surface. As a modification, suitably shaped rib-like or pillar-like spacers are arranged on the top face of a flat base plate with intervals therebetween.

摘要： Partially devitrified porcelain compositions are provided which are comprised of a mixture, based on its oxide content, of barium oxide (BaO), magnesium oxide (MgO) or a mixture of magnesium oxide with certain other oxides (CaO,ZnO), boron trioxide (B.sub.2 O.sub.3) and slicon dioxide (SiO.sub.2). In accordance with this invention the porcelain compositions are applied to the metal core and fired to provide a partially devitrified porcelain coating on the metal core. The coating has a very low viscosity at its initial fusion point and then almost instantaneous high viscosity due to partial devitrification. The fired coating has a deformation temperature of at least 700.degree. C. and a high coefficient of thermal expansion of at least about 110.times.10.sup.-7 /.degree.C.
