MECHANISM AND THERMODYNAMIC CALCULATION IN FORMATION OF COMPOSITE ULTRAFINE NiTiN PARTICLES BY ACTIVE PLASMAMETAL REACTION

Composite ultrafine NiTiN particles were prepared by active plasmametal reaction method in a mixture of N₂-H₂-Ar gas atmosphere. The formation mechanism of these particles is discussed. Thermodynamic calculation of chemical reactions in gas phases has been done to analyze the possibility of reactions.
