本发明公开了一种气雾化制备粒径细化钛基球形粉末的方法，该方法为：一、将钛基原料与锡料装入熔炼坩埚中，然后置于真空感应熔炼气雾化设备的熔炼室中进行真空感应熔炼；二、待所述钛基原料与锡料经真空感应熔炼融化后，充入氩气保护，再对位于熔炼坩埚底部的石墨导流管进行加热，钛基原料与锡料融化后产生的熔融液经加热的石墨导流管自由落至雾化室，经真空感应熔炼气雾化处理后得到雾化粉末，在收集罐中得到钛基球形粉末。本发明采用向钛原料或钛合金原料中引入锡元素用降低熔炼后得到熔融液的粘度，使得在气雾化时易于被破碎，制得的粉末的粒径变细，其中，钛基球形粉末中粒径小于45μm的粉末的收率不小于28％，粉末内部孔隙减少，空心粉数量降低

The invention discloses a method for preparing titanium base spherical powder with fine particle size by air atomization. The method is as follows: 1. The titanium base raw material and tin material are put into a smelting crucible, and then placed in the smelting chamber of vacuum induction smelting gas atomization equipment for vacuum induction smelting; Described, with titanium feedstocks and tin material after vacuum induction melting melting, filling the argon gas protection, and is located in the bottom of the crucible of smelting graphite heating of diversion pipe, titanium feedstocks and tin material after melting molten liquid heating graphite nozzle free fall to the atomizing chamber, the vacuum induction smelting atomization powder after aerosol treatment, titanium base spherical powder in the collection tank. The invention adopts the titanium or titanium alloy material raw material after the introduction of tin element in reducing smelting get melted liquid viscosity, resulting in aerosol is easy to be broken, when made of powder particle size and the titanium base of spherical powder of powder particle size is less than 45 microns in yield of not less than 28%, powder inside the pore reduced, to reduce the number of hollow powder
