摘要
Anhydrous lutetium chloride, which is not easy to prepare in other ways, was prepared by chemical vapor transport (CVT) method. Lu2O3 reacted with Al2Cl6 at 300 degrees C to produce LuCl3, which was then separated from other solids by means of CVT at a temperature gradient from 400 degrees C to 180 degrees C. Residual Al2Cl6 was removed by dry Cl-2-N-2 gas at 200 degrees C. The purity of the product was > 99.9%.
