等离子体法制备特种超细氧化铝

Specific Ultrafine Aluminium Oxide Prepared by the Plasma Technique

特种超细氧化铝近年来在各个工业领域得到了越来越广泛的应用并在国内外市场发展很快。本文根据氧化铝水合物及铝盐等在受热情况下的相变关系,介绍了特种氧化铝的各种制备方法及传统方法中所存在的问题,提出采用先进的等离子体技术制备特种超细氧化铝粉体材料的方法及优势。

Specific ultrafine powder of aluminium oxide has extensively been used in each the domain of the industry which is getting enormous economic results in the national and international market. It's present various kinds ways and the weakness of the technology in the specific ultrafine aluminium oxide processing which based on the diagrame of the phase changing of aluminium oxide with temperature. A advanced way which has a dominant position is put forward to prepare the specific ultrafine Al2O3. Undoubtedly. The way of plasma technique is a reliable and feasible means of processing ultrafine powder which will improve the backward situation and monotonous assortment of aluminium oxide in our country.
