Microsphere cenospheres in thermal insulation coating with powder shape from the coal ash, cementing well
The microspheres are a waste material arising in the process of combustion of hard coal. The product is made of spheres with a diameter of 10-800 microns, filled with gas, mostly CO2 and NO2. Sheaths of the spheres are 0.2-3 microns thick, what makes the microspheres have a great volume at a relatively low gravity. Material contains mainly: silicon oxide (SiO2), aluminum oxide (Al2O3), magnesium oxide (MgO), iron trioxide (Fe2O3), potassium oxide (K2O), calcium oxide (CaO) and vestigial admixtures of other metals. Chemical Composition SiO2 57,9 ± 5,0% AL2O3 35,8 ± 2,0% Fe2O3 1,5 ± 0,3% CaO 1,1 ± 0,2% MgO 1,6 ± 0,2% SO2/SO3 0,6 ± 0,3% K2O + Na2O 1,2 ± 0,4% TiO2 0,8 ± 0,3% Cl 0,2 ± 0,1%
