Caesium selanate is an inorganic compound, with the chemical formula of Cs2SeO4. It can form colourless crystals of the orthorhombic crystal system.
Preparation
caesium selenate can be obtained from the reaction of caesium carbonate and selenic acid solution:[2]
caesium selenate can also be prepared by the neutralization reaction of selenic acid and caesium hydroxide:[1]
Properties
caesium selenate can precipitate compounds such as CsLiSeO4·1⁄2H2O and Cs4LiH3(SeO4)4 in Cs2SeO4-Li2SeO4-H2O and its acidification system.[2] It can also form double salts with other metals, such as Cs2Mg(SeO4)2·6H2O, Cs2Co(SeO4)2·6H2O, etc.[3]
