大家知道,氧化铝中所含大部分水呈非结构水,即吸附水,它们容易在低温下除去。而少部分水在晶格力场的影响下处于结晶内部,除去这部分水要一直加热到1200℃。吸附水的数量取决于Al_2O_3的相组成,基本上由氧化铝中活性氧化铝的含量来决定。图中列举了9个一般工业氧化铝半年(取月平均组成)试样重量变化曲线。这些试样重
We all know that most of the water contained in alumina is unstructured water, that is, adsorbed water, they are easy to remove at low temperatures. While a small part of the water is in the crystalline interior under the influence of the lattice force field, and the water is removed until it is heated to 1200 ° C. The amount of adsorbed water depends on the phase composition of Al 2 O 3 and is basically determined by the amount of active alumina in the alumina. The figure lists the nine general industrial alumina six months (whichever is the average composition) sample weight curve. These samples are heavy
