Modified barium calcium titanate ferroelectric ceramic powder as well as preparation method and application thereof
The invention discloses modified barium calcium titanate ferroelectric ceramic powder and a preparation method and application thereof, and the modified barium calcium titanate ferroelectric ceramic powder comprises the following components in parts by mole: 100 parts of barium calcium titanate Ba (1-x) CaxTiO3 (x is more than or equal to 0.03 and less than or equal to 0.10), 0.5-1.5 parts of BaCO3, 0.05-0.2 part of ZrO2, 0.02-0.2 part of Mn3O4, 0.5-2.0 parts of rare earth oxide, 0.2-3.0 parts of MgO, 1.0-3.0 parts of SiO2 and 0.01-0.1 part of V2O5. According to the modified barium calcium titanate ferroelectric ceramic powder disclosed by the invention, the sensitivity of barium calcium titanate to a sintering schedule is reduced through BaCO3, ZrO2 and Mn3O4 with specific dosages, so that the modified barium calcium titanate ferroelectric ceramic powder can adapt to a large roller kiln, and the production qualification rate of a multi-layer ceramic capacitor can reach 95% or above.
本发明公开了一种改性钛酸钡钙铁电陶瓷粉体及其制备方法和应用，该改性钛酸钡钙铁电陶瓷粉体，包括以下摩尔份数的组分：100份钛酸钡钙Ba1‑xCaxTiO3(0.03≤x≤0.10)，0.5‑1.5份BaCO3，0.05‑0.2份ZrO2，0.02‑0.2份Mn3O4，0.5‑2.0份稀土氧化物，0.2‑3.0份MgO，1.0‑3.0份SiO2，0.01‑0.1份V2O5。本发明的改性钛酸钡钙铁电陶瓷粉体通过特定用量的BaCO3、ZrO2以及Mn3O4来降低钛酸钡钙对烧结制度的敏感性，使改性钛酸钡钙铁电陶瓷粉体能够适应大型辊道窑，且多层陶瓷电容器的生产合格率可达95％以上。
