Reaction of high-alumina refractory with .

Conclusions. The main cause of the failure of high-alumina refractory of mullite composition during service in vacuum furnaces is the chemical reaction of chromium vapors with the alumina, as a result of which a readily melting vitreous silicate substance is formed together with gaseous silicon monoxide and corundum with chromium dissolved in it.

Corundum - Wikipedia

In 1837, Marc Antoine Gaudin made the first synthetic rubies by reacting alumina at a high temperature with a small amount of chromium as a pigment. In 1847, J. J. Ebelmen made white synthetic sapphires by reacting alumina in boric acid. In 1877 Frenic and Freil made crystal corundum from which small stones could be cut.
