氧化铝陶瓷目前分为高纯型与普通型两种。氧化铝陶瓷干压成型技术于形状单纯且内壁厚度超过1mm，长度与直径之比不大于4∶1的物件。由于液压式压机冲程压力均匀，故在粉料充填有差异时压制件高度不同。而机械式压机施加压力大小因粉体充填多少而变化，易导致烧结后尺寸收缩产生差异，影响产品质量。
注浆成型是氧化铝陶瓷使用早的成型方法。由于采用石膏模、成本低且易于成型大尺寸、外形复杂的部件。注浆成型的关键是氧化铝浆料的制备。通常以水为熔剂介质，再加入解胶剂与粘结剂，充分研磨之后排气，然后倒注入石膏模内。由于石膏模毛细管对水分的吸附，浆料遂固化在模内。空心注浆时，在模壁吸附浆料达要求厚度时，还需将多余浆料倒出。
将颗粒状陶瓷坯体致密化并形成固体材料的技术方法叫烧结。烧结即将坯体内颗粒间空洞排除，将少量气体及杂质有机物排除，使颗粒之间相互生长结合，形成新的物质的方法。
连续热压烧结虽然提高产量，但设备和模具费用太高，此外由于属轴向受热，制品长度受到限制。热等静压烧成采用高温高压气体作压力传递介质，具有各向均匀受热之优点，很适合形状复杂制品的烧结。由于结构均匀，材料性能比冷压烧结提高30～50％。比一般热压烧结提高10～15％。
有些氧化铝陶瓷材料在完成烧结后，由于氧化铝陶瓷材料硬度较高，需用更硬的研磨抛光砖材料对其作精加工。通常采用由粗到细磨料逐级磨削，终表面抛光。此外激光加工及超声波加工研磨及抛光的方法亦可采用。有些氧化铝陶瓷零件需与其它材料作封装处理。（图/文www.yxwdcy.com）

Alumina ceramics are divided into high purity type and ordinary type two. Alumina ceramic dry press forming technology is limited to the shape and the inner wall thickness more than1mm alone, the length and diameter ratio greater than 4: 1. As the hydraulic press stroke uniform pressure, so the powder filling there are differences when pressing different height. Mechanical type compressor pressure size because of the powder filling much change, easily lead to sintering shrinkage difference, affect the quality of the product.

Injection molding is the earliest use of alumina ceramic forming method. Due to the adoption of the gypsum mold, low cost and easy forming of large size, the shape of complex parts. Injection molding is the key of alumina slurry preparation. Usually in water flux as medium, adding solution of glue and adhesive after grinding, fully exhaust, then pour into the gypsum mould. As a result of plaster mold capillary water absorption, slurry and solidification in mould.
