The word Cenosphere is derived from two Greek words Kens (hollow) and Sphaira (sphere). Cenospheres are light weight, inert hollow sphere comprising largely of silica & alumina and filled with air or inert gas. Cenospheres are a naturally occurring by product of the burning process of pulverized coal-fired boilers. Cenospheres are formed from coal combustion ash when it is in a molten state. Flowing with the combustion gas stream, the temperature of the molten particles is rapidly quenched, thereby ‘freezing in’ a spherical shape.
The numerous advantages of cenospheres, as mentioned above, coupled with the capability for of a lightweight construction aggregate are considered to be the significant drivers of the global cenospheres market. Cenospheres Market by Type (Gray Cenosphere, White Cenosphere), End-use Industry (Refractory, Construction, Oil & Gas, Automotive, Paints & Coatings), and market was valued at USD 346.8 Million in 2016 and is projected to reach USD 689.2 Million by 2022, at a CAGR of 12.16% from 2017 to 2022. This facilitates the development of new technologies and ensures a high quality product.
