Microwave dielectric property adjustment of CoZrNb2O8 ceramics by CaTiO3 addition

Temperature stable microwave dielectric ceramics CoZrNb2O8-xCaTiO3 (x = 1/60 ~ 1/10) were fabricated by a solid-state technique. The phase formation and sintering behavior were detected for the purpose of structure–property relationship exploration. Appropriate rate of CaTiO3 addition was benefit to the sintering temperature decrease of CoZrNb2O8. From x = 1/50 to x = 1/10, unexpected CaNb2O6 and Ti2Nb10O29 phases both formed, consequent on the...
