Co-doped barium titanate ceramic dielectric material as well as preparation method and application thereof
The invention relates to a co-doped barium titanate ceramic dielectric material, the co-doped barium titanate ceramic dielectric material comprises a main body material and a doping material, the main body material comprises BaTiO3 particles, the average particle size of the BaTiO3 particles is 80-140 nm, and the doping material comprises MgO, SiO2, MnO2 and Ho2O3. BaTiO3 is used as a main body material, so that the process complexity can be reduced, and the cost can be saved. According to the invention, the average particle size of the main body BaTiO3 particles is 80-140nm, and the doping material is added, so that the crystal grain growth easily occurring in the sintering process can be effectively inhibited, and finally, the ceramic dielectric material with the average particle size of 160-230nm can be obtained.
本发明涉及一种共掺杂钛酸钡陶瓷介电材料，所述共掺杂钛酸钡陶瓷介电材料包括主体材料和掺杂材料，所述主体材料包括BaTiO3颗粒，所述BaTiO3颗粒的平均粒径为80‑140nm，所述掺杂材料包括MgO、SiO2、MnO2和Ho2O3。本发明以BaTiO3作为主体材料，能够降低工艺复杂程度，节约成本。本发明通过使用主体BaTiO3颗粒的平均粒径在80‑140nm，通过添加掺杂材料，可以有效抑制烧结过程中容易出现的晶粒长大，最终能够得到平均粒径在160‑230nm的陶瓷介电材料。
