A comparison between hot-hydrolysis and sonolysis of various Mn(II) salts.
A variety of manganese salts ranging from completely soluble and ionized to insoluble compounds have been subjected to ultrasonic radiation in aqueous medium at pH approximately 8.3. All of the manganese salts yielded a product identified as nanoparticles of Mn(3)O(4), expect for MnCO(3), which yields of mixture of phases. The characteristics of the products obtained are compared with those obtained under vigorous stirring conditions. The shapes of nanocrystals varied from sharp-edged crystals to smooth particles.
