SRT能源中心高級(jí)總監(jiān)Barbara Heydorn對(duì)這種新的制鈦工藝進(jìn)行了簡(jiǎn)單介紹。它是利用等離子弧首先將氫分子打破成氫原子，然后氫原子與氯化鈦反應(yīng)生產(chǎn)煙霧狀的鈦，煙霧狀的鈦再經(jīng)快速冷卻成型變?yōu)殁伔邸RT已成功利用這種工藝在實(shí)驗(yàn)室制備出了純鈦，目前正在進(jìn)行工業(yè)化推廣前的深入研究，以期提高利用該工藝生產(chǎn)鈦粉的產(chǎn)量并降低生產(chǎn)成本。然而，將一項(xiàng)新的技術(shù)真正推廣到實(shí)際生產(chǎn)中并非易事。麻省理工學(xué)院材料化學(xué)專業(yè)的Donald Sadoway教授講道，企業(yè)采用新的工藝需要投入大量資金購(gòu)買設(shè)備、新建廠房，但是傳統(tǒng)觀念認(rèn)為金屬工業(yè)領(lǐng)域已經(jīng)發(fā)展成熟，最適宜的工藝已被開發(fā)并采用，因此新工藝很難得到資金支持。
