Cenospheres (aluminosilicate microspheres) are hollow aluminosilicate glass ceramic beads ranging in size from 400-500 microns 20-50mkm (most often from 100 to 250 microns), which are formed during high-temperature combustion of pulverized coal.
The chemical composition of the main component of the cenospheres is silicon oxide SiO2 (45-60%), aluminium oxide Al2O3 (15-40%), iron oxide Fe2O3 (1.0-10%), calcium oxide CaO (1.5- 4.5%), potassium oxide K2O (2.0-4.5%) and other certain oxides that make up the balance of the content are typically less than 1.0%.
Due to the unique set of physical and chemical characteristics of the cenospheres, they are used in the manufacturing of various composite materials. They are used in solving technical issues that require: reduction in the weight material with a low thermal conductivity, high strength, volume efficiency, increased resistance to erosion and aggressive environments.

Oil and gas industry: Accelerating the process and improving the efficiency of well drilling; increasing the life of drilling equipment; drilling fluids and plug cements of low density and high strength. Construction: ultralight and ultra-lightweight concrete; high-strength and low-density thermal and acoustic insulation boards; increased adhesion of concrete or brick walls, excellent leveler. dry mortars, lime and liquid mortars, cements, plaster, insulating roof coatings and soundproofing materials - lightweight, smooth surface, low cost, heat resistant, shrinkage resistant. sensitizer for the use of emulsion BBs. paints - resistance to chemical corrosion and light, thermal insulation, smoothness. Styrofoam: Aircraft, spacecraft, ship construction - low density and moisture absorption, high mechanical properties of materials for vibration damping, insulation and thermal protection. Ceramics: Refractory materials and coatings, insulation materials. Plastics Epoxy resins: production of polyethylene - improving strength and abrasion resistance. production of bearings, cameras, furniture and its accessories - tensile strength, impact strength, hardness, resistance to heat and light. Profiled materials, pipes, plates - dimensional stability, rigidity, heat resistance; TV housings, auto parts - compressive strength, bending elasticity, shrinkage reduction.
