Cenospheres 

 

During coal combustion in thermal power stations, ash particulates are generated. Amongst these particulates are small hollow particles with a density lower than that of water. These particles are called Cenospheres and can be seen magnified in the adjacent figure 1, (human hair included for scale)

 
 
 
Their unique chemical and physical properties i.e. inert, low density, high melting point, good insulating properties make them suitable for a vast range of industrial applications, from paint, plastics, resins to refractory bricks and many more.
 
 
General applications of Cenospheres:
 
 
 
Brake linings: Shoe sole​s: Body putty:
​​​
Paint: Insulating refactory bricks: Aerospace coatings:
Tile Cement:​​
