12047-79-9 Usage
Description
Barium nitride, with the molecular formula Ba3N2 and a molecular weight of 439.9944 g/mol, is a ceramic material that has been reported to be metastable and sublimes in the temperature range of 915 to 1050°C. It is characterized by its yellowish-brown color and is available in a -20 mesh size with 99.7% purity. However, the existence of barium nitride is doubtful, as there is no report of its formation or properties to date.
Uses
1. Used in Optical Materials:
Barium nitride is used as a dopant in optical materials, specifically for white emitting LEDs, due to its unique properties that enhance the performance of these devices.
2. Used in Synthetic Precursors:
Ba3N2 serves as a synthetic precursor for the production of ternary metal nitrides, which are essential materials in various industrial applications.
3. Used in Flux Growth Medium:
Barium nitride is utilized as a flux growth medium for the growth of gallium nitride (GaN), which is a significant material in the semiconductor industry.
4. Used in H-ionic Conductors:
Barium-nitride-hydride is one of the few documented H-ionic conductors, exhibiting a sharp increase in ionic conductivity at temperatures above 525 K. This property makes it potentially useful in the development of new materials for energy and electronic applications.
5. Used in the Production of Transition Metal Nitrides:
Ba2N has been employed to produce other subnitrides through bulk thermal or filament-initiated reactions of mixed powders of transition metal chlorides and Ba3N2. This process results in the formation of transition metal nitrides (TiN, ZrN, HfN, VN, V2N) in good yield, which are valuable materials in various industries.

Check Digit Verification of cas no
The CAS Registry Mumber 12047-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,4 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12047-79:
(7*1)+(6*2)+(5*0)+(4*4)+(3*7)+(2*7)+(1*9)=79
79 % 10 = 9
So 12047-79-9 is a valid CAS Registry Number.
