Refractory Cenospheres Ash Hollow Microspheres

Hollow Ceramic Microspheres,Ash Cenosphere

low density 0.35-0.45 g/cc

210-850um  300um  150um  100um

Hollow silica-alumina microspheres (cenospheres) are recovered from fly ashes formed at coal-fired thermoelectric power stations (TEPS).  

1.The properties of microspheres recovered from fly ashes are similar tomicrospheres industrially produced from melts,and much (several fold) cheaper than industrially  produced ones.

2.The shape of Cenospheres is almost spherical, their surface is smooth, and their diameter is from 20 to 500 microns.They contain gaseous phase including mostly nitrogen, oxygen, and carbon oxide.

Benefits of Cenosphere

        Reduced Raw Materials Cost                       Improved Flowability

        Reduced Resin Demand                              Improved Insulation Values

        Reduced End Product Weight                      Resistant to Resin Absorption
