  • Patent number: 9447357
    Abstract: The invention relates to lubricating compositions and methods for producing same. The lubricating composition comprises a lubricating medium and the product of dehydration of natural minerals or a mixture of natural minerals, or of synthesized hydrates. The dehydration product contains the oxides MgO and/or SiO2 and/or Al2O3 and/or CaO and/or Fe2O3 and/or K2O and/or Na2O and has a particle size in a range of 100-100000 nm. The method for producing the lubricating composition comprises a step in which hydrates of metal and/or non-metal oxides are dehydrated at a temperature of from 300 to 1200° C., a step in which the dehydration product is stabilized by being kept at a temperature of from 700 to 1200° C. for a period of 1 to 3 hours, and a step in which the resultant product is mixed with a lubricating medium.

  • Patent number: 9388360
    Abstract: The invention relates to the production of materials which can be used in lubricating compositions for treating friction assemblies and also for restoring the friction surfaces of mechanism and machine parts. The composition is produced from the products of dehydration of natural and/or synthesized hydrates and/or mixtures thereof at an inherent water removal temperature and dehydration product stabilization temperature of 300-1200° C. The composition contains oxides from the series MgO and/or SiO2 and/or Al2O3 and/or CaO and/or Fe2O3 and/or K2O and/or Na2O and is a garnet-shaped conglomerate consisting of a nanograin and an amorphous binding phase. The size of the conglomerate is in a range of 100-100000 nm and the size of the nanograin is in a range of 2-2000 nm. The claimed method includes a step for stabilizing the dehydration product at a temperature of 900-1200° C. for a period of 1-3 hours, which makes it possible to form a stable conglomerate structure.
