Abstract
Способ получения пентафторида ниобия и/или тантала, включающий взаимодействие металлических ниобия и/или тантала с фторирующим агентом, отличающийся тем, что в качестве фторирующего агента используют фторид меди в соотношении не более 4 моль фторида меди на 1 моль металлического ниобия и/или тантала, предварительный нагрев до 500°С и термическая или вакуумная отгонка образующихся пентафторидов ниобия и/или тантала.A method of producing niobium pentafluoride and / or tantalum, comprising reacting niobium metal and / or tantalum with a fluorinating agent, characterized in that copper fluoride is used as a fluorinating agent in a ratio of not more than 4 mol of copper fluoride per 1 mol of niobium metal and / or tantalum, preheating to 500 ° C and thermal or vacuum distillation of the resulting niobium and / or tantalum pentafluorides.
