| production method | 1 0.2 ~ mg of metal neodymium and less than the amount of metal HgI2 in 7 × 50mm quartz tube, vacuum was applied to P = 666.61 x 10-6PA and sealed. The quartz tube was placed in a muffle furnace and the temperature was slowly raised to 500 °c for 2H and then slowly cooled over 8H. The disappearance of the orange-red HgI2 indicated the completion of the reaction. One end of the tube was placed in a small furnace for the distillation of the mercury beads for separation from the product. 2. Add 1g of NH4I into a hard glass tube (inner diameter 10mm, length 60cm, one end closed), add 1g of a mixture of Nd2O3 and 6g of NH4I, and insert the reaction tube into an electric furnace, the length in the electric furnace was 22cm, and the tube portion outside the electric furnace was slightly inclined downward. The reaction tube was heated at 350 ° C. And occasionally rotated until there was no condensation of water in the tube part outside the furnace. It took about 4H for the reaction to be completed. The reaction tube was sealed and cooled to room temperature by sublimation of excess NH4I under high vacuum at 250 °c until no more condensed solids were observed in the unheated portion. |
