鋁鈣合金可作为炼鋼的脫氧剂及冶炼稀有金属的还原剂,高浓度的鋁鈣合金也可进一步真空蒸餾以制取金属鈣,同时鋁基鈣合金是一种有效的牺牲阳极材料。因此,研究經济的制取鋁鈣合金的新方法是有意义的。 Eiichi Fujita将氧化鈣与鋁相混合(3:2克分子),在温度1,060℃、真空度10~(-3)毫米汞柱下得到30～35%鋁鈣合金。Mantell将氧化鈣在熔融鋁浴中热至1,500—1,600℃,也制得鋁鈣合金,当以細粒鋁和石灰混合制团后放入熔融鋁浴中,合金合鈣量可达50%。Mantell的結果我們无法复証,得到合金合鈣仅1%左右。真室鋁热还原氧化鈣法制取金属鈣的主
Aluminum-calcium alloy can be used as steelmaking deoxidizer and smelting rare metal reductant, high-concentration aluminum-calcium alloy can be further vacuum distillation to obtain metallic calcium, while calcium aluminum alloy is an effective sacrificial anode material. Therefore, it is significant to study the economical new method of preparing Al-Ca alloy. Eiichi Fujita mixes calcium oxide with aluminum (3: 2 molecules) to obtain a 30-35% aluminum-calcium alloy at a temperature of 1,060 ° C and a vacuum of 10 -3 mmHg. Mantell calcium oxide in the molten aluminum bath to 1,500-1,600 ℃, also made of aluminum-calcium alloy, when mixed with fine-grained aluminum and lime into the molten aluminum bath, alloy calcium content up to 50%. The results of Mantell we can not reaffirmed, get alloy calcium only about 1%. Real room aluminum thermal reduction of calcium to take the main method of metal calcium
