过去认为,铝酸钠溶液碳酸化分解(下面简称碳分)时,氢氧化铝是以三水铝石或拜耳石形式呈固相析出。后来又证实了在某些条件下亦可以假一水软铝石形式的一水氢氧化铝析出。氢氧化铝的析出机理可归结如下:当碳酸气
In the past that the sodium aluminate solution carbonic acid decomposition (hereinafter referred to as carbon), aluminum hydroxide is in the form of gibbsite or Bayerite solid precipitation. Later it was confirmed that aluminum hydroxide monohydrate precipitated in the form of boehmite under certain conditions was also precipitated. The precipitation mechanism of aluminum hydroxide can be summarized as follows: When carbon dioxide gas
