Abstract

Natural and artifi cial aluminosilicates are relevant research objects due to their wide using in medicine, food and chemical industries, and in agriculture. The aim of the work is to study the possible changes under the infl uence of a weak pulsed electromagnetic fi eld of the atomic structure of powdery samples of three minerals clinoptilolite KNa2Ca2(Si29Al772·24H2O, montmorillonite Ca0.2 (AlMg)2Si4O10(OH)2·4H2O and palygorskite MgAlSi4O10(OH)·4H2O, belonging to the group of natural
aluminosilicates, in which silicon-oxygen and aluminum-oxygen tetrahedra are linked by a common oxygen atom. The results of studies by X-ray diffraction and ultra-soft X-ray emission spectroscopy showed that 48 hours after exposure of a weak pulsed electromagnetic fi eld to 71 mT for 30 seconds, the atomic and electronic subsystems of mineral samples still kept changes.
The infl uence of a weak pulsed electromagnetic fi eld on the atomic structure of minerals manifested itself differently in three samples in the form of one or two additional weak superstructural lines in diffractograms. The infl uence of a weak pulsed electromagnetic fi eld on the local environment of silicon by oxygen atoms in silicon-oxygen tetrahedra was manifested in the form of changes in the fi ne structure of the ultra-soft X-ray emission spectroscopy silicon Si L2,3 spectra, indicating the restoration of stoichiometry of silicon suboxides SiO1.8 in the composition of aluminosilicates of the initial powders
into stoichiometry equal to or close to silicon dioxide SiO2, in all three minerals.
