超细氧化铝粉末制备技术

The Preparation Technique of Ultrafine Alumina Powders

系统地介绍了超细氧化铝粉末的各种制备方法 ,将各种制备技术分别按气相法、液相法、固相法分类。并在其基本原理的基础上 ,主要介绍了CVD法、惰性气体凝聚、硫酸铝铵热解、碳酸铝铵热解、有机铝盐及无机铝盐溶胶—凝胶法及机械粉碎法等制取超细氧化铝粉末工艺及其优缺点。

Introduction is systematically made about many kinds of preparation techniques of ultrafine alumina powders.The preparation techniques are classified according to gas-phase,liquid-phase and solid-phase methods.On the basis of its fundamental principles.technologies and its advantages and disadvantages of CVD,inert gases agglomeration, thermal decomposition of ammonium aluminum sulphate and ammonium aluminum carbonate,organic and inorganic alumina sol gel and mechanical crushing methods are mainly introduced.
