scandium oxide Sc2o3

Because of the unique physical and chemical properties of Sc2O3 products, since the 1980s, it has been better applied and developed in many high-tech and industrial sectors.  At present, China and the world's Sc2O3 in alloy, electric light source, catalyst, activator and ceramics and other fields of application described in the following.  

Application of alloy  

At present, al-SC alloy made of scandium and aluminum has the advantages of low density (Sc is 3.0g/cm3,Al is 2.7g/cm3, high strength, high hardness, good plasticity, corrosion resistance and thermal stability, etc. Therefore, it has been well applied in the structural parts of missiles, aerospace, aviation, automobiles and ships.  And gradually to civilian, such as sports devices (hockey and baseball handle), computer and mobile phone cases, with high strength, stiffness and light weight characteristics, very practical value.  

Scandium mainly plays a role in the modification and grain refinement of alloy, so that the formation of new phase Al3Sc type and presents the characteristics of excellent performance.  Al-sc alloy has formed a series of alloy series, such as Russia has reached 17 kinds of Al-Sc series, China also has several alloys (such as Al-Mg-SC-Zr and Al-Zn-Mg-SC alloy).  The characteristics of this kind of alloy can not be replaced by other materials, so from the perspective of development, its application development and potential is very large, it is expected to become a major application in the future.  If Russia has industrialized production, and for light structural parts for rapid development, China is also accelerating the development and application, especially in the aerospace and aviation prospects.
