氧化铝，以化学式Al2O3表示的话，其所指十分明确，即仅以铝元素和氧元素组成的化合物。在广义上，氧化铝往往被认为是铝的氧化物与铝 的氢氧化物等的统称，是由铝、氧和氢组成的一类化合物。因此，氧化铝又被分为无水氧化铝和水合氧化铝。 无水氧化铝即我们所熟知的α-Al2O3、β-Al2O3、γ-Al2O3等不同晶型的氧化铝，国内发现的无水氧化铝的晶型有九种以上。水合氧化铝实际上 是由Ａl3+、O2-和OH-构成的，其中并不存在真正的水分子，只是由于习惯沿用至今，其水合物经过高温锻烧后都可转变成α-Al2O3。常见的 水合氧化铝为工业氢氧化铝、拜铝石、诺铝石、拟铝石、软铝石、硬铝石、托得石等。 由此可见，氧化铝家族是多么的庞大，应用注定十分广泛，这也难怪各行各业都有不同氧化铝厂家的身影了。下面我们盘点6种常见的氧化铝 产品及其代表性企业。 从应用来说，氧化铝可分为冶金级氧化铝与非冶金级氧化铝（即精细氧化铝）。冶金级氧化铝只用作金属铝的生产原料，工业生产中使用的铝 材料均来源于它，看似应用单一，但其占比可达氧化铝的90%以上，精细氧化铝占比不足10%。可以说冶金级氧化铝产量基本代表了某个国家 的氧化铝整体产量。 我国是氧 ...
