A new high-Q, low-temperature microwave dielectric ceramic with composition Li 2 Cu 0.2 Mg 0.8 Ti 3 O 8 and a cubic spinel structure was prepared at 900–975°C for 2h by the conventional solid-state route. The ceramic sintered at 950°C for 2h exhibits optimum dielectric properties with a moderate dielectric constant of 28.1, a high quality factor of 34,300GHz...
Single-phase dielectric ceramics Li 2 Cu x Zn 1−x Ti 3 O 8 (x=0–1) were synthesized by the conventional solid-state ceramic route. All the solid solutions adopted Li 2 MTi 3 O 8 cubic spinel structure in which Li/M and Ti show 1:3 order in octahedral sites whereas Li and M are distributed randomly in tetrahedral sites with the degree...
