Dilute acid-soluble platinum compounds were synthesized in a molten KOH-BO medium at 500C in the presence of Ca(OH). The acid-soluble platinum compounds formed on the surface of CaCO generated during heat treatment. The platinum compounds consisted of a Pt-O bond, a diborate group, and AlO, and the network structure of these components can incorporate K and Ca ions. The compounds were extracted in 1M HCl (aq), and the Pt extraction efficiency was 83%. The morphology of the Pt compounds varied depending on the surface conditions of the reaction containers. When the compounds were synthesized on an alumina plate whose surface was modified with liquid sodium, fibrous platinum compounds were generated, and their crystallinity was higher than that obtained on an untreated alumina plate.
