Neodymium Disilicide Powder, NdSi2, CAS 12137-04-1

Neodymium Disilicide (NdSi2) Powder Synthesis Process 

• Method 1:

1. Mix Nd, Si, and Hg, then place the mixture in a quartz tube.
2. Heat the tube in an electric furnace at approximately 450°C for 10–12 hours.
3. Remove excess Hg through bent-tube distillation.
4. After all, Hg is collected at the cold end, and the product is at 450–600°C at the hot end of the tube.

• Method 2:

1. Weigh Nd₂O₃ and Si according to the stoichiometric ratio and continuously evacuate.
2. React the mixture in a vacuum in an alumina boat.
3. Quickly and completely remove SiO formed during the reaction.
4. Control the reaction temperature at 1100–1600°C, avoiding temperatures above 1600°C to prevent impurities from container reactions.
