一、前言氧化铝既使在金属氧化物中,也最具有取得平衡的性能,它作为陶瓷用的基本原料由来已久。众所周知,99%以上的氧化铝是用拜耳法生产的。其他的氧化铝,如高纯或超细Al_2O_3,由于须具有更优异的性质是用拜耳法以外的各种方法生产的。所谓高纯氧化铝,大部分都是属于后者。目前,这种氧化铝,已在集成电路基板、插件、电子元件等方面得到使用。 First, the preface Alumina even in the metal oxide, but also the most balanced performance, as a basic raw material for ceramics with a long time. It is well known that more than 99% of alumina is produced by Bayer process. Other aluminas, such as high purity or ultrafine Al 2 O 3, are produced by various methods other than the Bayer process due to their superior properties. The so-called high-purity alumina, most of them belong to the latter. Currently, such alumina has been used in integrated circuit substrates, inserts, electronic components and the like.
