Nitride tuning of lanthanide chromites [PDF]
Chemical Communications, 2016 LnCrO3−xNx compounds with Ln = La, Pr and Nd represent one of the few examples of chromium oxynitrides and the first chromium oxynitride perovskites. Hole-doping of LnCrO3 through O2−/N3− anion substitution suppresses the antiferromagnetic transition far less drastically than cation substitutions.

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Rate and Mechanism of Reduction-Dissolution of Chromite in Liquid Slags
High Temperature Materials and Processes, 2013 The dissolution of chromite from the Bushveld Complex of South Africa in liquid slags was studied in the temperature range 1550° to 1665°C under argon gas. The slag compositions were similar to those of ferrochromium production and stainless steel making.
