High dielectric strength 95 alumina ceramic material and preparation method thereof
The invention relates to a high dielectric strength 95 alumina ceramic material, which is prepared from the following materials by mass: 95 parts of alpha-Al2O3; the content of SiO2 is 3.0 to 3.5 parts; 0.4 part of MgO; 0.9 to 1.4 parts of CaO; the content of Y2O3 is 0.1 to 0.2 part; and 10 parts of a PVA solution. According to the method, a proper amount of SiO2, MgO, CaO and Y2O3 sintering aids are added into aluminum oxide, and the 95 aluminum oxide ceramic which is fine in grain, uniform in microstructure and excellent in physical performance is obtained through ball milling, granulation, forming and sintering.
本发明涉及一种高介电强度95氧化铝陶瓷材料，由以下材料按照质量份数制成：α‑Al2O3为95份；SiO2为3.0～3.5份；MgO为0.4份；CaO为0.9～1.4份；Y2O3为0.1～0.2份；PVA溶液10份。本发明通过向氧化铝中添加适量的SiO2、MgO、CaO和Y2O3烧结助剂，经球磨、造粒、成型、烧成得到晶粒细小、微观结构均匀、物理性能优良的95氧化铝陶瓷。
