描述
别名 刚玉;金刚砂;活性氧化铝;矾土;铝氧;三氧化二铝;
生化机理 Aluminum oxide is an inorganic compound used as a grinding or blending agent. In addition, Aluminum oxide can be essential in protein extraction as a component in the preparation of tissues. Aluminum oxide is a source of aluminum in reactions, an abrasive agent, and as a refractory material. Furthermore, Aluminum oxide has a relatively high thermal conductivity of 30 Wm?1K?1. Also Aluminum oxide can act as a catalyst in a variety of reactions such as the Claus process and in the dehydration of alcohols to alkenes.
应用 用作研磨剂，并用于制坩埚、陶瓷、耐火材料和人造宝石等。用作制铝原料，并可形成不同晶形的氢氧化铝。
