METHOD OF PRODUCING NITRIDE MATERIAL Russian patent published in 2019 - IPC C04B35/581 C01F7/00 C01F7/50

Abstract RU 2689581 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemical production of nitride materials and can be used in making ceramic, metal-ceramic and composite materials. To obtain a nitride material, a powdered material is obtained from sodium hexafluorotitanate, aluminium trifluoride and aluminium metal in molar ratio of 1:4:8.5 with gaseous nitrogen at temperature of 1100–1200 °C and rarefaction with subsequent condensation of final nitride material. Aluminium trifluoride and residual sodium tetrafluoroaluminate are removed by distillation.

EFFECT: obtaining nano-sized powdered nitride material.

1 cl, 1 dwg
