Product Description
Yttrium oxide
Molecular formula: Y2O3
Molecular weight: 113.16
CAS: 11130-29-3
Character
White powder, density 5.01g/cm3, melting point 2410 C, insoluble in water and alkali, soluble in acid. 

Application domain: 
Additive for iron and steel and nonferrous alloys. Usually FeCr alloy containing 0.5-4% yttrium yttrium can enhance the oxidation resistance and ductility of these stainless steel; MB26 alloy adding y-rich mischmetal, the mechanical properties of the alloys have been significantly improved, can replace part of the strong Aluminum Alloy for stress components of the aircraft; In the Al-Zr alloy by adding a small amount of yttrium rich rare earth. Can improve the conductivity of the alloy; Alloy has been used in most of the domestic wire factory; Adding yttrium in copper alloy, improve the conductivity and mechanical strength; Silicon nitride ceramic material containing yttrium aluminum 2% and 6%, can be used to develop the engine components; For power Nd: YAG laser beam of 400 watts to drilling, the large component of cutting and welding and other mechanical processing for electron microscopy; Fluorescence screen Y-Al garnet single crystal films, fluorescence of light scattering of high brightness, low absorption, high temperature resistance and Resistance to mechanical wear performance is good; For high yttrium alloy structure can be used in aviation and other requirements of low density and high melting point of the occasion; For yttrium doped SrZrO3 high temperature proton conductive material, production of fuel cell and electrolytic cell and hydrogen requirements the high solubility of gas sensor has important significance; For high-temperature spraying materials, nuclear reactor fuel diluent, permanent magnetic material additive and the electronics industry for getter etc...
