Methods of chemical analysis of initial reagents, pН-measurement of filter solutions, thermogravimetry, and X-ray diffraction have studied the interaction inter phosphoric acid and industrial carbonate precipitation. The nature of the compounds is installed in obtained of the dry air, calcined at 660 and 850 оC the reaction product mixture. The temperatures of dehydration, interaction, and phase transitions are determined. It is shown that the obtained results can be used in the process of the
