Abstract

Abstract α-Be3N2 powder was obtained by reacting Be metal with dry, flowing N2 at 1600 K. The product contained 5.9(7) wt.% of BeO. The anti-bixbyite structure suggested earlier was verified through Rietveld refinement on the basis of X-ray powder data (Ia3 (#206); a = 814.518(6) pm). The optical band gaps of α-Be3N2, Mg3N2 and Ca3N2 are compared with newly measured values for Mg3N2, Ca3N2 and CaMg2N2.
