• Cenosphere Download

    The process of burning coal in thermal power plants produces fly ash containing ceramic particles made largely of alumina and silica. These particles form a part of the fly ash produced in the burning process. They are produced at the high temperature of 1450 to 1700 degrees Celsius through complicated chemical and physical transformation. Cenospheres are the lighter particles that are contained within the fly ash. These are hollow, hard-shelled, ultra low density spheres, which form unique free flowing powders. Their chemical composition and structure varies considerably depending on the composition of coal that generated them.
