The following selenites were studied by the solubility method, thermal analysis, powder X-ray diagrams, and IR molecular spectroscopy: CaSeO3.H2O, CaSeO3 (two crystalline modifications), Ca(HSeO3)2.H2O, CaSe2O5, and Ca2S3O8 (hitherto unknown). Exact conditions for the preparation of the selenites and their bonding relations are given.
