Abstract

Effect of pH on the formation of strontium titanyl oxalate starting from strontium nitrate and potassium titanyl oxalate has been investigated. Thermal analysis revealed the formation of stoichiometric strontium titanyl oxalate only at pH 2.5. Progressive increase in pH led to the formation of strontium titanyl hydroxy oxalate at pH 7.0. Further increase in pH up to 9.0 yielded only a physical mixture of strontium oxalate and titanium hydrous oxide.
