Ultra-fine niobium and tantalum powders were synthesized by hydrogen reduction from niobium ( V ) chloride and tantalum ( V ) chloride in argon atmosphere at 950 ℃ .

在氩气气氛中，在950℃条件下用氢气还原相应的气态 氯化物分别制取了铌和 钽的超细微粉末。

Crystalline titania films ( anatase and rutile ) with excellent in vitro bioactivity were deposited through interactions of titanium and hydrogen peroxide solutions containing trace tantalum chloride under temperatures lower than 100 ℃ .

利用含微量 TaCl5的双氧水溶液在低于100℃温度下与钛金属之间的化学反应，在钛金属表面直接生成具有良好生物活性的锐钛矿与金红石混合结构晶态二氧化钛薄膜。
