Scandium sulfate is an inorganic chemical compound of scandium from the group of sulfates .

Extraction and presentation

Scandium sulfate can be obtained by evaporating a solution of scandium nitrate mixed with sulfuric acid and heating the residue.

properties

Scandium sulfate is a colorless, crystalline solid that is very soluble in water. However, small amounts of sulfuric acid in the water greatly reduce the solubility. It has a trigonal crystal structure with the space group R 3 (space group no.148) . At room temperature, the compound is present as a pentahydrate, which turns into the dihydrate at around 100 ° C. There is also an octahydrate. From about 600 ° C the compound decomposes and up to 850 ° C scandium oxide is formed . Template: room group / 148

use

Scandium sulfate is used in solution for the germination of seeds.
