ABSTRACT:
Insulator material for microcircuit construction comprising a glaze composition intermixed with a proportion of refractory oxide particles sufficient to make the fluidity of the material considerably less than the fluidity of the glaze composition by itself, at temperatures just sufficient to fuse the glaze. The particles are preferably of an oxide which will gradually diffuse, but not melt, into the glaze, and will tend to raise the glaze fusion temperature during heat treatments in which the glaze is fused. Alumina, beryllia, titania, zirconia, calcium oxide or magnesium oxide may be used, preferably in proportions from 10 to 40 per cent by weight, and with particle sizes in the range from 2 to 30 microns. The material may be sprayed or screen-printed in a suitable medium. Successive layers may be applied and heat-treated at temperatures sufficient to fuse the glaze of the top layer without distorting underlayers previously fused at the same temperature.
