摘要：

Phosphate compound with mixed cations, NaBaPO4 can be a new candidate of microwave dielectric ceramics with the basis of the systematically investigations of the ternary compound series of AMPO(4) (A=Li, Na, K; M=Ca, Sr, Ba). Ceramics with single phase of NaBaPO4 can be obtained under our optimized experimental sintering conditions for this compounds above, whereas its microstructures and microwave dielectric properties are strongly influenced by the sintering temperatures and holding times. Relatively dense microstructures can be obtained under the sintering conditions of 910 degrees C/0.5h, with unique combination of microwave dielectric properties as epsilon=8.279, Qxf=10237GHz (11.4GHz) and (f)=+19.07ppm/degrees C, and fast sintering characteristics (0.25-0.5h) are the inherent properties of such phosphate compound.
