Preparation
editCerium(IV) selenate can be obtained by reacting cerium(IV) hydroxide with hot selenic acid, and the tetrahydrate can be crystallized from the solution.[2]
Properties
editCerium(IV) selenate has a space group of Pbca, and its unit cell parameters are a = 9.748 Å, b = 9.174 Å, and c = 13.740 Å.[1][3]
The tetrahydrate has orthorhombic space group Fddd with unit cell dimensions a = 27.31, b = 12.38, c = 5.736 Å.[2]
It hydrolyzes when exposed to water and can be reduced to trivalent cerium using hydrogen peroxide.[4]
