Synthesis and Characterization of the Rocksalt Phases (Ca,Th)(N,O) and (Sr,Th)(N,O)

Alkaline-earth rich (Ca,Th)(N,O) and (Sr,Th)(N,O) can be prepared from reactions of the binary nitrides at 1000°C. Th 2N 2O impurities in the starting material, Th 3N 4, resulted in oxygen incorporation in the final compound. The black products crystallize in the rocksalt structure type in which the...

Description
Summary:Alkaline-earth rich (Ca,Th)(N,O) and (Sr,Th)(N,O) can be prepared from reactions of the binary nitrides at 1000°C. Th 2N 2O impurities in the starting material, Th 3N 4, resulted in oxygen incorporation in the final compound. The black products crystallize in the rocksalt structure type in which the cations are disordered ( a = 5.101(5) Å and a = 5.241(2) Å, respectively). They exhibit semiconducting behavior.
