氧化鋁陶瓷目前分為高純型與普通型兩種。高純型氧化鋁陶瓷系Al2O3含量在99．9％以上的陶瓷材料，由于其燒結溫度高達1650—1990℃，透射波長為1～6μm，一般制成熔融玻璃以取代鉑坩堝：利用其透光性及可耐堿金屬腐蝕性用作鈉燈管；在電子工業(yè)中可用作集成電路基板與高頻絕緣材料。
普通型氧化鋁陶瓷系按Al2O3含量不同分為99瓷、95瓷、90瓷、85瓷等品種，有時Al2O3含量在80％或75％者也劃為普通氧化鋁陶瓷系列。其中99氧化鋁瓷材料用于制作高溫坩堝、耐火爐管及特殊耐磨材料，如陶瓷軸承、陶瓷密封件及水閥片等；
95氧化鋁瓷主要用作耐腐蝕、耐磨部件；85瓷中由于常摻入部分滑石，提高了電性能與機械強度，可與鉬、鈮、鉭等金屬封接，有的用作電真空裝置器件。（圖/文lxyzxyh.cn）

Alumina ceramics are divided into high purity type and ordinary type two. High purity alumina ceramics department of Al2O3content in more than 99.9% of the ceramic material, due to its high sintering temperature of 1650℃ - 1990 ℃, the transmission wavelength of 1～ 6 μ m, generally made of molten glass to replace platinum crucible : the use of its transparency and alkali metal corrosion for sodium lamp; in the electronic industry can be used as the substrate of the integrated circuit and the high frequency insulation material.
Common type of alumina ceramic by different Al2O3 content is divided into99 porcelain,95 porcelain,90 porcelain,85 porcelain and other varieties, sometimes Al2O3 content in 80% or 75% are classified as ordinary alumina ceramic series. One of 99alumina ceramic material used for high temperature crucible, refractory furnace tube and the special wear-resistant material, such as ceramic bearings, ceramic seals and valves etc..
