Abstract
The invention provides moisture-proof treatment of a finished product in the production process of a high-pressure ceramic capacitor. The treatment is characterized in that: barium titanate, bismuth titanate and calcium titanate are taken as raw materials. A temperature compensation high-frequency microwave capacitor medium material is prepared by mixing the materials, adding into polyvinyl alcohol for sintering and molding, and sintering at the temperature of about 1,360 DEG C. In the capacitor material sintered according to a ceramic formula, the compressive strength value is 25 kv/mm, the dielectric constant epsilon is equal to 50, and the quality factor Q is equal to 5*10<-4> under the alternating working current of 1 MHz. During practical preparation, a preparation method comprises the following steps of: weighing barium carbonate (BaCO3), bismuth oxide (Bi2O3), calcium carbonate and titanium dioxide (TiO2) according to a certain mixture ratio, performing ball milling, mixing, and drying to obtain barium titanate (BaTiO3), bismuth titanate (Bi2O3.3TiO2) and calcium titanate CaTiO3 at the temperature of 1,200-1,400 DEG C; and burdening a modifier from La2O3, Nd2O3, Sm2O3, Bi2O3, TiO2, Nb2O5 and Ta2O5 serving as raw materials, adding 0.2-0.6 percent of zinc oxide (ZnO) and 0.5-2 percent of zirconia (ZrO2), performing ball milling and mixing for 24 hours, drying, adding 8 percent by weight of polyvinyl alcohol for granulating, and sintering at the temperature of 1,360 DEG C.
