Satoh (j ) has measured the heat contents of three chromium nitride samples at three temperatures each (372.6, 598.8, and 784.2 K), in an ice calorimeter. DeLuca and Leitnaker (1 ) have reevaluated his heat contents and presented C data for CrN in the temperature range 298-1400 K. Their values above 400 K are adopted and joined smoothly with the low temperature C data (10) near 350 R. C data above 1400 K are obtained by graphical extrapolation.

Boron nitride is a white slippery solid. One B atom and one N atom together have the same number of valency electrons as two C atoms. Thus boron nitride has almost the same structure as graphite, with sheets made up of hexagonal rings of alternate B and N atoms joined together. 

Air-sensitive Ca3CrN3 can be made from reaction of the binary nitrides at 1350 C in sealed Mo tubes [131], The structure contains planar CrN, groups and CaNj square pyramids N atoms center Ca5Cr octahedra. The anion-centered description of the structure begins from the rocksalt structure viewed down a 4-fold axis. If one removes 1 /4 of the octahedra in a layer and then shears the layers, one obtains a layer of the Ca3CrN, structure. The layers are joined by edge-sharing as shown in Fig. 17.
