The corundum deposit in Yingshan county, Hubei province, was found in the 50's to 60's of this century. For some reasons, corundum in the deposit has not been exploited. The authors studied systematically the mineralogical characteristics of corundum from Yingshan county, determined various physical properties and parameters and observed inclusions of the corundum. By using electron microprobe, X-ray powder analysis and visible spectrum analysis, the chemical composition, crystal structure and spectral characteristics were analyzed. Besides, experimental study on its heat treatment was conducted. The authors consider that the corundum from Yingshan county has the characteristics of coarse grains, good morphology and light color. It can be blue-yellow- and flesh red-colored by means of heat treatment. But gem-quality stones are rare owing to well-developed fractures, inclusions concentrated inclusions and poor transparence. More should be done on the technique of healing the fractures in order to raise the production of gem-quality stones from these corundums.
