| Use | Production method calcium nitride can be obtained by reacting elemental calcium in a nitrogen stream. The fine fibrous calcium metal purified by distillation was placed in a nickel boat and heated at 450 ° C. For 3-4H in a stream of pure N2. Because at this temperature, calcium metal undergoes a crystal transformation (hexagonal crystal Ca → body-centered cubic Ca), the metal lattice structure becomes loose, so that the nitriding reaction speed is very fast, and calcium nitride can be obtained. |

Abstract:
The present invention relates to a calcium nitride synthesis process comprising the aid of an injector (5) the molten zinc-calcium alloy is sprayed in the form of droplets into a reactor (6) comprising nitrogen at high temperature. The generated calcium nitride is collected in a collection unit (7) in the lower part of the reactor (6). The zinc contained in the droplets is evaporated, condensed on the cooled walls of the reactor (6) and reused for the preparation of further alloys. The zinc-calcium alloy is obtained by electrolyzing calcium chloride in an electrolytic cell (11) in which the cathode (14) is a solution comprising molten zinc.

12013-82-0 - A study on the lattice deformation of calcium azide under high pressure
Author:
Xiaoxin Wu , Zhu Hongyang , Ma Yanzhang
Abstract:
we have carried out high-pressure X-ray synchrotron radiation experiment, high-pressure Raman scattering experiment, high-pressure far-infrared absorption experiment and high-pressure mid-infrared absorption experiment on calcium azide powder, the maximum pressures reached in the experiment were 54 GPa,19.2 GPa,23 GPa and 31 GPa, respectively. No structural phase transition was found in the whole experimental pressure range. The zero modulus of calcium azide and the pressure derivative of the bulk modulus obtained in the experiment are B0 = 41.22±1.14 GPa,B0 & prime;= 5.3±0.04, this value is higher than all alkali metal azides due to the difference in ionic nature of the bond between the metal and the azide. In order to analyze and identify the vibration modes observed in all experiments, we use the CESTEP module to compare the

| Production method | Calcium nitride can be produced by reacting elemental calcium in a nitrogen stream. The fine fibrous metal calcium purified by distillation is placed in a nickel boat and heated at 450 ℃ for 3~4h in pure N2 gas flow. Because the metal calcium undergoes crystal transformation at this temperature (hexagonal crystal Ca→body-centered cubic Ca), the metal lattice structure becomes loose, so the nitriding reaction speed is very fast, and calcium nitride can be obtained. |
