FIELD: chemistry.
SUBSTANCE: in the method of obtaining nanoparticles with a crystal lattice, mainly consisting of Z-sulphate (Z=magnesium (Mg), calcium (Ca), strontium (Sr) or barium (Ba)), nanoparticles are synthesised through growing a crystal from a source of Z-ion and a source of sulphate ions in a liquid phase reaction mixture. The reaction mixture contains a non-aqueous solvent with coordinating properties, which serves as a component, which regulates the growth of particles. The non-aqueous solvent is chosen from polyatomic alcohols and dimethylsulphoxide DMSO. It is also possible to obtain doped nanoparticles of sulphates of alkali earth metals. The nanoparticles have size ranging from 0.2 to 50 nm.
EFFECT: simplification of the process of obtaining nanoparticles of sulphates of alkali earth metals, which can homogenously disperse in water.
