A simple thermal decomposition–nitridation route to nanocrystalline chromium nitride (CrN) by the reaction of ammonium dichromate and Mg powders

Nitridation of Cr–urea complex into nanocrystalline CrN and its antiferromagnetic magnetostructural transition study

“…28 In addition, Ma et al simultaneously employed thermal decomposition and nitridation to obtain CrN nanoparticles by reaction of (NH 4 ) 2 Cr 2 O 7 and magnesium metal in an autoclave at 550 °C. 29…”

“…28 In addition, Ma et al simultaneously employed thermal decomposition and nitridation to obtain CrN nanoparticles by reaction of (NH 4 ) 2 Cr 2 O 7 and magnesium metal in an autoclave at 550 1C. 29 Combination strategies of two or more techniques are another very common way to produce nanostructured CrN. For example, the required nanostructured replica of chromium metal oxide, sulfides, or organometallic complexes can be obtained from different processes like sol-gel, chemical reduction, solvothermal, electrospinning, etc.…”

Effect of annealing temperature on CrN microspheres synthesized by CAP technology

“…Therefore, much effort is being put into the development of CrN films for industrial applications, but there are only a few reports on preparation of CrN nanostructures. The synthesis of metallic nitrides nanomaterials have attracted lots of research interests since the last decade of 20th century, many approaches have been developed for the preparation of chromium nitride, including cathodic arc plasma (CAP) technology [7] , direct thermal solid-state reaction [6] , thermal nitridation synthesis [8] , simple nitrification route [9] , plasma-assisted molecular beam epitaxy [10] , ammonia nitridation approach [11] , simple thermal decomposition-nitridation route [12] , benzene-thermal route [13] , and so on. CAP is a mature technology for CrN deposition and has been optimized in the past years.…”
