An LizC0s/Na2C03/KzCOJ eutectic melt has been taken as a typical example of a molten carbonate system, and the dissolution behaviour of the oxides of nickel and copper in the melt have been investigated at 873 K. The solubility products of CuO and NiO in the melt have been estimated to be 8.9 X lo-'
Polarized single crystal absorption spectra, in the spectral range 40 000-5 000 cm-1, were obtained on Co 2+ in trigonally distorted octahedral oxygen fields of buetschliite-type K2Co(SeO3) 2 (I), KzCoz(SeO3) a (II) and zemannite-type K2Co2(SeOa)3.2H20 (III). Site symmetries of Co 2+ are 3m (Dad) in
