Abstract
Low-temperature (1 023 K) vacuum reduction of a mixture of zirconium dioxide with calcium is used to obtain a powder with an active zirconium content of 98.4 % (wt.). Physicochemical properties that determine the thermal and ignition characteristics of the powder and pyrotechnic compositions based on it are studied.
