GLASS-CERAMIC AS DIELECTRIC FOR USE IN HIGH-FREQUENCY RANGE

摘要

PROBLEM TO BE SOLVED: To provide a glass-ceramic which is particularly suitable as a dielectric for use in the high-frequency range, in particular as a dielectric resonator, as an electronic frequency filter element, or as an antenna element.SOLUTION: The glass-ceramic has at least the following constituents in mol% on an oxide basis, 5-50% of SiO, 0-20% of AlO, 0-25% of BaO, 0-25% of BaO, 10-60% of TiO, and 5-35% of REO, where Ba can be partly replaced by Sr, Ca, or Mg, where RE is a lanthanide or yttrium, and where Ti can be partly replaced by Zr, Hf, Y, Nb, V, or Ta.
