Cenospheres are hollow spheres made up of silica or alumina usually filled with inert gas or air and are light in weight. These are typically produced after the coal combustion in the thermal power plants. In many specialized applications, Cenospheres have become a widely needed filler or additive. For instance, automotive brake rotors, polymeric composites, lightweight cements, mullite-coated diesel engine components, energy absorption and electromagnetic shielding applications. Cenospheric materials were recently reported to be used to manufacture composite straps and composite railway sleepers as an additive or filler in a polymer cement matrix. Cenospherical elements are especially promising with their spherical and hollow morphologies, with high resistance to splitting.
The size of the global market for Paints & Coatings and other end-User Industry are expected to Drive Cenospheres is expected to reach $715 million by 2030, expanding at a compound annual growth rate (CAGR) of 12.5%.
Cenospheric density ranges from 0.2 g / cc to 2.6 g / cc. The availability is relatively low as it makes up a small portion of the weight of fly ash. For the Cenospheres type that contains heavy iron oxides in the silica matrix of spheres, a higher density up to 2.9 g / cc could be found. The cenospheric particle size is much larger than fly ash particles, with a diameter between 5 and 500 meters. The thickness of the shell ranges from 2 to 30 micrometres. The three principal features that put cenospheres in demand are size, form and density.
Paints & Coating
The current Cenospheres dividing methods are divided into two groups. One is wet and another is dry separation method. The mechanism of wet separation is based on the density differences between solid and liquid particles. Cenospheres in the paint- and industrial coating industry have many applications because of their additional qualities. Cenospheres are typically used in indoor radiation control coatings, which give them an advantage over those which merely try to limit the thermal conductivity
Cenospheres also serve for production of plastics and polymers, which help to prevent thermoplastic shrinking and thermosetting plastics by their reform-able shapes or strength. Cenosphere is used for many years in the pharmaceutical industry, as small balls can serve as almost ideal transportation devices when drug-coated. Cenospheres are providing emerging opportunities along with the future effects of major drivers and challenges that support the managers to make cost-effective decisions in favour of the business. The increasing demand from end use companies including lacquers, refractory, building and oil & gas, which is expected to soon reach the next level on the market. Limited raw material sources and lack of quality control in developing nations are nevertheless important factors which could impede industrial growth.
The Gray Cenospheres category will have the highest economic growth in future years due to its large applications throughout the industrial sector. The demand will also grow, as the gray cenosphere is more common than the white cenosphere in fly-ash. The demand is increasing for India's gray cenosphere suppliers as they provide quality material that contains a low alumina content and a high silica and iron content.
Due to the region's increasing oil, gas and automotive industries, North America is expected to be a most rapidly growing cenosphere market during the projected period. Cenospheres are almost 30% lighter than traditional resins and nearly 75% lighter than most of the minerals used as fillers or extender. Cenosphere is expected to serve as main source of growth in the overall cenospheric market in all end user industries during the projected period.
