About Cenospheres or Microsphere

Microspheres/ Cenosphere

Cenospheres/ Microspheres are lightweight, inert, hollow spheres composed mainly of silica and alumina, produced as a by-product of coal combustion in thermal power plants. Ranging from gray to white, these microscopic spheres are used as fillers in construction, refractory, oil, Gas drilling and paint industries due to their high strength, low density, and buoyancy.

Cenospheres are a unique byproduct of coal combustion, typically generated during the burning of coal in thermal power plants. These hollow, lightweight particles are made up of silica, alumina, and iron oxide, and they possess a number of fascinating properties that make them valuable in a variety of industrial applications. The spheres have high crush strength, pressure resistance, excellent thermal insulation properties, are non-toxic and non-hazardous. The particle shape allows for an easier application and provides a smoother finish.
