Californium(III) carbonate is a synthetic, highly radioactive inorganic chemical compound composed of californium and carbonate with the chemical formula Cf
2(CO
3)
3.[1]
Properties
Californium(III) carbonate features californium in its dominant +3 oxidation state. Similar to other trivalent actinide and lanthanide carbonates, neutral californium(III) carbonate is sparingly soluble in aqueous solutions.[1] In the presence of excess carbonate or bicarbonate ions, it forms soluble anionic carbonate coordination complexes.[2]
Because all californium isotopes are intensely radioactive, solid compounds and solutions of californium(III) carbonate experience significant self-heating and radiolytic breakdown.[3]
Preparation
Californium(III) carbonate can be synthesized by reacting aqueous trivalent californium salts with soluble alkali metal carbonates or ammonium carbonate in aqueous solution under controlled inert atmosphere.
