Corundum - Rausser College of Natural Resources

2002-8-26  Chromium enters into the structure of the corundum (diffuses into the corundum). This is a slow process, so chromium enrichment only occurs in the surface layer. This is sufficient to produce a strong color enhancement that is difficult to detect by eye. Diffusion treatment for sapphires is similar to that for any corundum

Corundum - an overview ScienceDirect Topics

G.J. MacPherson, in Treatise on Geochemistry, 2007 1.08.3.4 Hibonite. Although corundum is predicted to be the first major-element condensate from a hot solar gas, that phase is quite rare in CAIs and instead hibonite is the most commonly encountered aluminate. From an isotopic point of view especially, hibonite is one of the most important of all CAI phases (e.g., Ireland, 1988; Ireland et al ...
