Product performance
Scandium Carbonate is a water insoluble Scandium source that can easily be converted to other Scandium compounds, such as the oxide by heating (calcination).

Applications
Scandium Carbonate can be used in the preparation of other scandium compounds as well as in high-temperature systems because of its resistance to heat and thermal shock. It is a helper material in glass composition. Also, Scandium Carbonate is a kind of reagent.

Storage condition
Should be sealed in a dry, cool environment, should not be exposed to the air for long, the protection of moisture to be reunited, influence dispersing performance and use effect.
