| titleOfInvention | Preparation method of rare earth halide |
| abstract | The invention provides a preparation method of rare earth halide, which comprises the following steps: will LnX 3 ·nNH 4 Heating X powder in a rare earth oxide crucible to obtain rare earth halideThing LnX 3 (ii) a The LnX 3 ·nNH 4 The rare earth elements in the X powder are the same as those in the rare earth oxide crucible; wherein Ln is selected from one of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc and Y, X is halogen, and n is more than 0 and less than or equal to 12. The preparation method provided by the application can obtain high-purity, anhydrous and oxygen-free rare earth halide; the anhydrous high-purity rare earth halide obtained by the method can grow high-purity blocky single crystals or fibrous single crystals with excellent scintillation property. |
