氧化镓制备

1.向三氯化镓GaCl3的热水溶液中加NaHCO3的高浓热水溶液，煮沸到镓的氢氧化物全部沉淀出来为止。用热水洗涤沉淀至没有Cl-为止，在600℃以上煅烧则得到β-Ga2O3。残留NH4Cl时，在250℃就和Ga2O3反应，生成挥发性GaCl3。

2.这是高纯Ga2O3的制法。以高纯金属Ga为阳极，溶解于5%～20%H2SO4溶液里，向溶液加氨水，冷却，将Ga(NH4)(SO4)2反复结晶，在105℃干燥，在过量氧的条件下在800℃灼烧2h，则得到纯度为9999%～99.9999%的产品。

3.称取1kg99.9999%的高纯镓放入三颈烧瓶中，加入高纯硝酸，使镓全部溶解，然后过滤，滤液倒入三颈烧瓶中，移至电炉上蒸发（在通风橱中进行），浓缩到接近结晶时，将溶液移置于大号蒸发皿中蒸发至干。将蒸干的Ｇａ（ＮＯ３）３放在马弗炉中进行灼烧，温度控制在550℃，灼烧５ｈ，待冷却后取出成品，得１．２ｋｇ高纯氧化镓。
