Product 1

HCID 20841688Carbonic acid, scandium(3+) salt (3:2)

Procedure

Adding 6 m3 of scandium chloride solution (0.5 mol/L) into a reactor containing 18.3 m3 of the above calcium bicarbonate solution to react for 3 hours at 35° C., and controlling the pH value of mother liquor at 8.0, scandium ions are precipitated. And then scandium carbonate is obtained after filtration, washing and drying.

Workup

  1. customto react for 3 hours at 35° C.
  2. customare precipitated
