Synonyms: metalsbasis); CALCIUM NITRIDE; tricalcium dinitride; calciumnitride(ca3n2); CalciuM nitride (99%-Ca); Calciumnitride,(metals basis); CALCIUM NITRIDE, -200 MESH, 99%; Calcium nitride;
Production method Calcium nitride can be prepared by reacting elemental calcium in nitrogen flow. The fine fibrous metal calcium purified by distillation is placed in a nickel boat and heated at 450°C for 3-4 hours in a purified N2 gas stream. Because the crystal form of metal calcium changes at this temperature (hexagonal crystal Ca→body-centered cubic Ca), the metal lattice structure becomes loose, so the nitridation reaction speed is very fast, and calcium nitride can be obtained.
