GLASS-CERAMIC AS DIELECTRIC IN THE HIGH-FREQUENCY RANGE

摘要

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