  • Low dielectric inorganic composition for multilayer ceramic package
    Patent number: 5071793
    Abstract: A ceramic composition for forming a ceramic dielectric body having a dielectric constant of less than about 4.2. The composition is formed from a mixture of finely divided particles of 25-50 vol. % borosilicate glass and 50-75 vol. % high silica glass. The borosilicate glass comprises approximately 20-35 wt. % B.sub.2 O.sub.3 and approximately 60-80 wt. % SiO.sub.2. The high silica glass contains essentially 0.5-1 wt. % alumina, 1-5 wt. % B.sub.2 O.sub.3 and approximately 95-98 wt. % SiO.sub.2. The composition can be fired at a temperature of less than 1000.degree. C.
