Abstract
The invention provides a method for preparing sponge titanium from potassium fluotitanate by aluminothermic reduction, comprising the following steps: a reaction step: aluminum and zinc are mixed under a vacuum state, and the mixture is then reacted with potassium fluotitanate; a distillation step: KF, AlFand Zn generated by reaction are distilled out under a vacuum state; and a cooling step: sponge titanium is obtained subsequent to banking cooling. The invention further provides another method for preparing sponge titanium from potassium fluotitanate by aluminothermic reduction, comprising the following steps: a reaction step: aluminum and magnesium are mixed under a vacuum argon introduction condition, and the mixture is then reacted with potassium fluotitanate; a distillation step: KF, AlF, MgFand Mg generated by reaction are distilled out under a vacuum state; and a cooling step: sponge titanium is obtained subsequent to banking cooling.
