Urea; alkaline earth metals; carbonates; infrared spectra.

The metal carbonate, MCO₃ (M = Ca, Sr and Ba), was synthesized by a novel method of reacting aqueous solution of each of Ca²⁺, Sr²⁺ and Ba²⁺ salts with urea at high temperature, ∼ 80°C. The reaction products were characterized through elemental analysis and infrared spectra. The infrared spectra of the products are the same as those of the corresponding commercially obtained carbonates. A general reaction describing the formation of MCO₃ is proposed.
