添加晶种碳酸化分解制取砂状氧化铝

Producing sandy alumina by adding seed through carbonation decomposition

用数学方法,研究了添加晶种碳酸化分解制取砂状氧化铝的多种因素,在提高氢氧化铝强度的工艺条件下,α-A l(OH)3经焙烧制得了符合技术指标的砂状氧化铝。

Many factors during the process of producing sandy alumina by adding seed through carbonation decomposition are studied in this paper by mathematic method.Sandy alumina that meets the technical parameters are made by roasting α-Al（OH）3 under the control of increasing the intensity of aluminium hydroxide.
