日本大阪钛有限公司研制成功一种制备细微钛粉的新技术.该新技术是一种将高频加热与气体雾化相结合的方法.高纯钛或钛合金经高频加热熔化,用压缩的氩气冲击熔体,即用氩气雾化钛,使之产生细小的钛粒。新技术的成本只是普通方法的一半.用气体雾化方法是对从坩埚流出的熔体喷射一种压缩气体.这种方法适于制备细微铁或镍粉.但是如果是钛及其合金会与氧化铝或石墨坩埚中的碳或氧发生反应,致使钛纯度降低且使坩埚受到腐蚀.因此,一般的气体雾化不适于钛或
Japan’s Osaka Titanium Co., Ltd. successfully developed a new technology for the production of fine titanium powder.This new technology is a combination of high-frequency heating and gas atomization method of high purity titanium or titanium alloy melting by high frequency heating, with compression Of the argon impact melt, that argon atomized titanium, so that the fine titanium particles. The cost of the new technology is only half that of the conventional method. The gas atomization method is the injection of a compressed gas from the melt flowing out of the crucible. This method is suitable for the production of fine iron or nickel powder, but if it is titanium and its alloys, The reaction of carbon or oxygen in alumina or graphite crucibles causes the purity of the titanium to be reduced and the crucible to be corroded Therefore, conventional gas atomization is not suitable for titanium or
