Abstract
Synthesis of Ba2La3Ti3NbO15 (BLTN) microwave ceramics by a simple and effective reaction-sintering process was investigated. The mixture of BaCO3, La2O3, TiO2 and Nb2O5 was pressed and sintered directly without any calcinations involved. BLTN ceramics could be obtained after 2–6 h sintering at 1430–1500 °C. A density 6.08 g/cm3 (98% of the theoretical value) after sintering at 1500 °C for 6 h. ɛr = 47 and Qf ∼ 2000 GHz and a τf value ∼+20 ppm/°C were obtained in BLTN ceramic sintered at 1470 °C/6 h.
