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.

99.9 % grade, high purity, has been tested and approved by leading industrial buyers, now open to export markets for your requirements. Granules/capsules can be used more productively and efficiently in your process management since its much lower energy consumption during integration.

We supply Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field). Bismuth is stable to oxygen and water but dissolves in concentrated nitric air. All bismuth salts form insoluble compounds when put into water. Applications Bismuth metal is used in the manufacture of low melting solders and fusible alloys as well as low toxicity bird shot and fishing sinkers. Certain bismuth compounds are also manufactured and used as pharmaceuticals. Industry makes use of bismuth compounds as catalysts in manifacturing acrylonitrile, the starting material for synthetic fibers and rubbers. Bismuth is sometimes used in the production of shot and shotguns. Bismuth in the environment The most important ores of bismuth are bismuthimite and bismite. Bismuth occurs naturally as the metal itself and is found as crystals in the sulphides ores of nickel, cobalt, silver and tin. Bismuth is mainly produced as a by-product from lead and copper smelting, especially in USA. The chief areas where it is mined are Bolivia, Peru', Japan, Mexico and Canada, but only to the extent of 3.000 tonnes per year. There is no reliable estimate of how much bismuth is available to be mined, but it seems unlikely than there will ever be a shortage of this metal.
