METHOD OF SYNTHESIS OF THE CRYSTAL PHASES OF THE MINERAL DIES FROM THE SOLUTIONS, HOT MELTS AND THE SOLID PHASES Russian patent published in 2006 - IPC B01D9/00 

FIELD: chemical industry; methods of synthesis of the crystal phases of the mineral dies.

SUBSTANCE: the invention is pertaining to the synthesis of the analogs of the natural crystals and offers the method of synthesizing of crystal phases of mineral dies from the solutions, hot melts and solid phases, in which provides for the treatment of the reaction mixture taken in the stoichiometric ratio defined according to the phase diagram of the analogs of the natural minerals selected from the following row: strontium-containing hydrosilicates, hydro garnets, hydroferrites, hydroalumoferrites, glasses, ceramics, with the UHF source with the frequency of 460 MHz and the wavelength of 65.2 cm or with the frequency of 2450 MHz and the wavelength of 12.3 cm, the power of 0.85-5.0 kW at the temperature of 80-1300°C within 0.5-6 hours. The invention allows to realize the express-synthesis of the analogs of the strontium minerals in the optimal conditions.

EFFECT: the invention ensures realization of the express-synthesis of the analogs of the strontium minerals in the optimal conditions.
