· The volatile scandiumβdiketonates are synthesised using acetylacetone (acac) and tetramethylheptanedione (tmhd) as coordinative ligands for CVD appliion. The Xray powder patterns are indexed and analysed and found to be orthorhombic and monoclinic phases for Sc(acac)3(1) and Sc(tmhd)3(2) respectively. The sublimation and evaporation kinetics have been analyzed using three .
mine production of scandium anywhere in the world today. The lack of secure supply has led to significant volatility in pricing, with scandium oxide prices ranging between 2,300/kg to 5,200/kg over recent years (Source: QYResearch Scandium Oxide Industry Research Center, 2014).
