 Properties: light yellow crystalline powder, equiaxed crystal scandium oxide structure, density 8.36 g/cm3, melting point 2367 ℃. Insoluble in water, soluble in acid, when exposed in air is easy to absorb carbon dioxide and water. 
 Application: Additive for metal halide, metal halide is a gas discharge lamp, which is developed on the basis of high-pressure mercury lamp, and its characteristics in the light bulb filled with a variety of rare earth halides. Currently the main use of rare earth iodide, issued in the gas discharge lines of different colors of light. Holmium light in the material is used in the work of holmium iodide, in the arc area can obtain a higher concentration of metal atoms, thus greatly improving the radiation efficiency; for yttrium-iron-yttrium aluminum garnet or additives; holmium-doped yttrium aluminum garnet Stone (Ho: YAG) laser can be fired 2μm, 2μm laser on human tissue absorption rate, almost Hd: YAG high-three orders of magnitude. So with the Ho: YAG lasers for medical procedures, not only can improve the operation efficiency and accuracy, and thermal damage can be reduced to a smaller area. Free beam generated by holmium crystal to eliminate fat without generating excessive heat, thereby reducing thermal damage to healthy tissue, it was reported the U.S. with holmium laser treatment of glaucoma, patients can reduce the pain of surgery. 2μm laser crystals in China has reached international standards, should be vigorously developed and produced the laser crystal; in the magnetostrictive alloy Terfenol-D, you can also add a small amount of holmium, which reduces the saturation magnetization alloy required field; other doped holmium laser fiber can produce fiber, optical fiber amplifiers, fiber sensors, etc. In the optical fiber communication optical communication devices rapidly today play a more important role.
