Scandium(III) phosphate is an inorganic compound of scandium, with the molecular formula ScPO4.[1]
It also occurs naturally as the rare mineral pretulite.[2][3][4]
Preparation
It can be prepared by heating scandium oxide and dilute phosphoric acid for at least a week at 400°C, yielding anhydrous scandium phosphate. Lower temperatures produce hydrates and mixtures of hydrates.[1]
Properties
Anhydrous scandium phosphate crystalizes in the zircon structure.[1]
