描述
別名剛玉;金剛砂;活性氧化鋁;礬土;鋁氧;三氧化二鋁;
生化機(jī)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 Wm1K1. 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.
備注使用注意事項(xiàng):運(yùn)輸過程中必須保持包裝瓶的完整,本標(biāo)準(zhǔn)物質(zhì)在分析測量前應(yīng)進(jìn)行前處理，即250℃下真空脫氣至少5小時、并緩慢冷卻至室溫后再使用。樣品不能重復(fù)使用。
應(yīng)用用作研磨劑，并用于制坩堝、陶瓷、耐火材料和人造寶石等。用作制鋁原料，并可形成不同晶形的氫氧化鋁。
