摘要
A glass-ceramic composition for forming a glass-ceramic dielectric body having a dielectric constant of less than about 4.5, a firing temperature of less than about 950° C. and a sintered density of greater than 95% theoretical density. The composition is formed from a mixture consisting essentially of finely divided particles of 40-50 vol. % borosilicate glass and 50-60 vol. % cordierite. The borosilicate glass comprises approximately 20-35 wt. % B.sub.2 O.sub.3 and approximately 60- 75 wt. % SiO.sub.2. The exact particle size ratio of the cordierite to borosilicate glass that is used will depend on the proportions of the components, the desired fired density and the firing temperature. The mixture is fired at a temperature of less than 1000° C.
