摘要
研究了磷酸对铝酸钠溶液种分分解的影响。结果表明 ,磷酸不仅能加速和加深铝酸钠溶液的分解 ;而且有助于得到高活性、粒度相当的氢氧化铝晶种。该法生产上易于实施 ,磷酸便宜易得。
This paper studies the affection of phosphoric compound on hydrolization process of sodium aluminate solution with seed crystal. The result show that phosphoric acid can not only improve hydrolization of sodium aluminate solution, but also be helpful to obtain aluminium hydroxide crystal seed with high-activity and appropriate size. The technique is easy to actualize in production and phosphoric acid easy to buy by low cost.
