Abstract

Colorless and transparent corundum crystals were readily grown for the first time by a slow-cooling method of Li₂Mo₂O₇ flux. They looked blackish at a glance because they had inclusions in their center. The crystals formed as plate bounded by well-developed {0001}, {0112} and {1014} faces. They were up to 5 mm in size. The crystal habit changed to thin hexagonal plate-like crystals as they grew large. Li₂Mo₂O₇ flux was found to be a suitable flux for the growth of plate-like corundum crystals.
