Compared with the activity of sodium methoxide, sodium ethoxide, sodium isopropyl, sodium tert-butoxide, the best base catalyst was sodium tert-butoxide.
比较甲醇钠、乙醇钠、异丙醇钠和叔丁醇钠催化活性，叔丁醇钠为最佳的催化剂。

The LiTaO3 thin film was chosen as infrared sensing film and prepared by a sol-gel process using lithium acetate and tantalum ethoxide as starting materials.
The results show that the vapour pressure and the mass loss rate of tantalum propoxide, tantalum butoxide and niobium ethoxide are suited for chemical vapor deposition.
