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.
Cenosphere.
Cenosphere: A cenosphere is a lightweight, inert, hollow sphere comprised largely of silica and alumina and filled with air and/or gases. Cenospheres are a naturally occurring by-product of the burning process at coal-fired power plants, and they have most of the same properties as manufactured hollow-sphered products. Typical Properties of Cenospheres SiO2: 52 - 62% Al2O3: 32 - 36% K2O: 1.2 - 3.2% Fe2O3: 1 - 2% TiO2: 0.8 - 1.3% MgO: 1 - 2.5% Na20: 0.2 - 0.6% CAO: 0.1 - 0.5%
Khetan group is manufacturer and global supplier of processed cenosphere .We manufacture clean and graded cenosphere which have high compressive strength.The true density consistency will always give the result as expected.Our cenosphere provide all the benefits which are same as microsphere and can improve the properties and performance of many formulated products.
