WebApr 19, 2024 · Scandium has some interesting properties. It is silvery-white in color and has a melting point of 1541°c (2815°f). Its density is slightly higher than aluminum, making it very lightweight yet strong. In addition to being corrosion resistant, scandium also has a high electrical conductivity and thermal conductivity. WebAug 2, 2024 · Use Pt as the crucible container material. Perform the fusion at 1000 °C in a muffle furnace. Avoid flames since this fusion is difficult to perform in a flame due to the high melting point of the sodium carbonate. Most fusions are complete in 15 minutes and some require up to 45 minutes. Dissolve the fuseate in dilute HCl (1:1). grannies scottish macarrons
