China Fly Ash Balloons/Floating Cenospheres

Hollow Ceramic Microspheres,Refractory Cenosphere

210-850um  300um  150um  100um

 Cenosphere are lightweight, inert, hollow, nonmetallic spherical materials, composed largely of silica (SiO₂) and alumna (Al₂O₃) compositions of Cenospheres are similar with glass and ceramic.Those hollow glass particles have also been called hollow ceramic spheres and micro spheres. 

Benefits and Features of Using Cenospheres:

          Reduce the weight of end products and cost                             Increase the strength.

          Hollow Sphere                          Low Bulk Densities                     Low-cost

          High Compressive Strength      Low Thermal Conductivity          Good Sound Isolating

           Good Insulation.                     Stability in Chemicals                 Thermal Stability

          Non Inflammable                     Resistant to Water                      Low Shrinkage
