Preparation of Cr-Mg-N-O Ceramics by Spark Plasma Sintering

Cr1−x-Mgx-N-O powders, with Mg content in metallic elements (x=Mg/Cr+Mg) ranging from 0 to 0.5, were synthesized from CrN and MgO powders using mechanical alloying under nitrogen atmosphere. Densification of these original powders is carried out by the spark plasma sintering is performed under a 70...
