Abstract
Structural studies of calcium citrate obtained by IR irradiation of calcium carbonate and citric acid in various ratios by spectroscopic and X-ray structural analysis has been carried out. It is shown that in the obtained samples of calcium carbonate there are polymorphic states in the form of aragonite, vaterite, calcite, as well as ikaite and in calcium citrate complex calcium compounds with different coordination numbers are observed.
