NF3 is prepared with good yields by reaction between fluorine gas and an ammonium complex of a metal fluoride, such as (NH4)3AIF6, in solid phase. The metal flouride ammonium complex may be one additionally containing an alkali metal, such as (NH4)2NaAIF6. The gas-solid reaction is carried out preferably at temperatures above 80 C. and at relatively low partial pressures of fluorine in the gas phase of the reaction system, so that the reaction is easy to control.
