Study On Mechanism Of Magnesia Production By Reversion Reaction Process In Vacuum
MAGNESIUM TECHNOLOGY 2016(2016)
Abstract
The mechanism of magnesia production was investigated experimentally in reversion reaction process in vacuum. The results showed that the reversion reactions were exothermic reaction, the gas-phase reversion will commence as soon as a saturated gas mixture was cooled down. MgO and Mg2C3 were detected in the condensing tower by Mg vapors and CO during reversion reaction process below 1373K. The reversion reaction indicated that Mg and CO was not only occurred in MgO, but also yielded got Mg2C3. The main reaction was 6Mg(g)+4CO= Mg2C3+4MgO+C. A high purity metal magnesium product, was obtained in the the vacuum distillation process. The calculated peak value of reversion reaction ratio was less than 9%. Contrast the condensing product and purity magnesium distillation product, the condensing product had a filament crystallization and loose structure. But the purity magnesium product had a lump structure and good crystalline feature.
