Abstract:
A low temperature firing glass-ceramic substrate comprising a borosilicate glass, .alpha.-alumina, .gamma.-alumina, and mullite crystals crystallized out in a dispersed form from the borosilicate glass and the .gamma.-alumina, and a production process of the substrate. It is an object of this invention to provide a glass-ceramic substrate, which is low in dielectric constant and dielectric loss and high in strength and is useful for multilayer wiring.
