A glass-ceramic which is particularly suitable as dielectric for use in the high-frequency range, in particular as dielectric resonator, as electronic frequency filter element or as antenna element is disclosed. The glass-ceramic has at least the following constituents (in mol % on an oxide basis): 5-50% of SiO2, 0-20% of Al2O3, 0-25% of B2O3, 0-25% of BaO, 10-60% of TiO2, 5-35% of Re2O3, where Ba can be partly replaced by Sr, Ca, Mg, where Re is a lanthanide or yttrium and where Ti can be partly replaced by Zr, Hf, Y, Nb, V, Ta.
