[0042] Example 1
[0043] A kind of BaTiO 3 Base dielectric ceramics, chemical composition is (1-y)BaTi 1-x Ca x O 3-x -yBi(Zn 0.5 Ti 0.5 )O 3 , X=0.04, y=0.1.
[0044] Above BaTiO 3 The preparation method of base dielectric ceramics includes the following steps:
[0045] (1) Preparation of BaTi 0.96 Ca 0.04 O 2.96 Powder: According to BaTi 0.96 Ca 0.04 O 2.96 Chemical composition weighing raw material: BaCO 3 (99%), TiO 2 (99%), CaCO 3 (99%), put the weighed raw materials into a planetary ball mill tank, and mix them with a certain proportion of absolute ethanol and zirconium balls. The specific parameters are: the milling time is 8h, and the speed is 1200r / min;
[0046] Pour the ball-milled slurry into a beaker and place it in a blast drying oven for 24 hours. The oven temperature is set to 100°C. The dried powder is crushed with a mortar, and then placed in a round crucible at 1190°C Pre-fired for 2h; the pre-fired powder is dried after the second ball milling to obtain the require...
