The interaction of chromium oxide with different forms of carbon in a wide temperature range is investigated. The phase composition and morphology of the resulting powder product are examined. It is established that Cr3C2 and Cr7C3 single-phase chromium carbide is formed at 1400 and 1500°C, respectively. It is shown that the smallest particle size (0.85 μm) is due to the mixed structural state of Cr7C3 and Cr3C2 carbides.
