Core-shell structure high-electric-strength titanium oxide-based dielectric powder as well as preparation method and application thereof
The invention relates to core-shell structure high-electric-strength titanium oxide-based dielectric powder and a preparation method and application thereof. The core-shell structure high-electric-strength titanium oxide-based dielectric powder is provided with a core-shell mechanism, TiO2 particles serve as an inner core, and a CaO-MgO2-Al2O3-SiO2 coating layer serves as an outer shell; wherein the molar ratio of CaO to MgO to Al2O3 to SiO2 in the coating layer is (0.7-1.1):(0.9-1.2):(1.7-2.3):(7.5-8.3), and preferably, the molar ratio of CaO to MgO to Al2O3 to SiO2 is 1:1:2:8.
本发明涉及一种核壳结构高耐电强度氧化钛基介质粉体及其制备方法和应用，所述核壳结构高耐电强度氧化钛基介质粉体具有核壳机构，内核为TiO2颗粒，外壳为CaO‑MgO‑Al2O3‑SiO2包覆层；所述包覆层中CaO、MgO、Al2O3和SiO2摩尔比为（0.7～1.1）：（0.9～1.2）：（1.7～2.3）：（7.5～8.3），优选为1:1:2:8。
