The influence of electromagnetic field (EMF), created in the frequency range from 100 to 200 kHz, on the calcium carbonate crystallization from supersaturated aqueous solutions on the model system CaCl 2 - NaHC O 3 - FeSO 4 at 80°C at a molar ratio of CaCl 2 :FeSO 4 (100:1), on the steel surface and in bulk was studied. It was found out that iron ions reduce the poorly soluble scales formed total mass (mainly CaCO 3 ) by ∼12%, both adhered to the steel surface and in the solution volume. Under the EMF influence, the adhered crystals amount on the steel surface in the Fe 2+ ions presence decreases by 40% and in the absence by 14%. In volume, under the EMF influence, on the contrary, the crystals’ number increased by 15% in the iron ions’ presence, in the iron ions absence it decreased by ∼ 6%. In the Fe 2+ ions presence and under the EMF influence, a decrease in the aragonite formation was noted while the calcite and vaterite content increased.
