铝酸钠溶液碳酸化分解是燒结法生产氧化铝的重要工序之一。碳酸化分解的条件对氧化铝的质量和分散度有重大影响。二氧化硅在铝酸钠溶液碳酸化分解过程中的行为,对分解有着巨大作用。以前发表的什瓦莰曼、阿拉凱良、沃罗柯娃的文章认为,在硅量指数为340～500的铝酸钠溶液碳酸化分解过程中,在分解初期析出的水合铝硅酸钠,便是后来氢氧化铝结晶的中心。
Carbonate decomposition of sodium aluminate solution is one of the important processes for the production of alumina by sintering. The conditions of carbonation decomposition have a significant effect on the quality and dispersion of alumina. The behavior of silica in the carbonation and decomposition of sodium aluminate solution has a great effect on decomposition. The previously published articles by Shivaman, Alakailiang, and Vorokoff believed that in the process of carbonation and decomposition of sodium aluminate solution with a silicon content of 340-500, hydrated sodium aluminosilicate precipitated at the initial stage of decomposition, It is the center of the aluminum hydroxide crystallization.
