GLASS-CERAMIC AS DIELECTRIC IN THE HIGH-FREQUENCY RANGE

摘要

A glass-ceramic is disclosed which can be used in particular as a dielectric and which has at least the following constituents (in mol % on oxide basis): SiO2 1-50, Al2O3 0-20, B2O3 0-25, TiO2 10-70, RE2O3 0-35, wherein RE is lanthanum, another lanthanoid, or yttrium, wherein Ti may be replaced in part, preferably up to 10%, by Zr, Hf, Y, Nb, V, Ta, and wherein the porosity is less than 0.5%.
