Abstract

The paper considers the use of multi-pulsed synthesis facility based on coaxial magnetic plasma accelerator for plasma dynamic synthesis of iron oxide powder with a high content of ε-Fe2O3 phase. It is shown that the multipulsed operation of coaxial magnetic plasma accelerator considerably lowers the discharge-current amplitudes and one-pulse power supply, thereby decreasing the dynamic load in the whole system. It is found that the formation of the increased amount of ε-Fe2O3 phase up to ~70 wt.% depends on the number of sequential pulses of power supply. Optimization studies determine the most favorable operating conditions with regard to an effective performance of the proposed system and maintaining the phase composition of the product obtained.
