| Abstract: | ELECTRONIC COMPONENTS & MATERIALS(China) ,Vol.18,No.5,P.9 10(Oct.1999).In Chinese. Ba (Mg 1/3 Ta 2/3 )O 3ceramic prepared by co deposition and its sintering characteristics are studied.The sintering temperature reduced by 180～250℃ as compared with the conventional method.Of the compact ceramics acquired at 1 400℃, Q×f =65 000 GHz, ε r =23～25; τ f =(0～3)×10 -6 ℃,when f=10 GHz and t =-20～+60℃.(3 refs.) |
