采用温度梯度带熔炼法，通过硅铝熔融带穿过单晶硅，将铝引入固体硅，测定了1016 ~ 1622 K温度范围内铝在硅中的固体溶解度。在1450 K左右，最大溶解度为4.3 X 10 -4。铝在固体硅中相对于纯固态无限稀释时的活度系数为：RT in γ 0 Al(s) = 93200（±1000）- 14.5（±0.8）T (J/mol) （1016-1622 K）。
The solid solubilities of aluminum in silicon in the temperature range of 1016-1622 K have been measured by introducing aluminum into solid silicon by passing a molten silicon-aluminum zone through single crystalline silicon with temperature gradient zone melting method. The maximum solubility was found to be 4.3 X 10 -4 in molar fraction around 1450 K. The activity coefficient of aluminum in solid silicon at infinite dilution relative to the pure solid state was determined as RT In γ 0 Al(s) = 93200(±1000) - 14.5(±0.8)T (J/mol) (1016-1622 K).
