Product Description

     We Hebei Daguangming Ind.Group is the diversified company, Cenosphere is one of our main products,the total production is 10000Mts per year,We got ISO:9001:2008 Qualityf Certificate,OHAS14001:2008 Certificate.Our Products are exported to USA,Middle-East widely and used in oil-well with heat resistance and other features.
       It is also called flying ash hollow ball, grayish white, thin wall and hollow, very light weight, bulk density of 720kg/m3 (heavy), 418.8kg/m3 (light), diameter of about 0.1 mm, closed and smooth surface, small thermal conductivity, refractory degree is less than 1610 DEG C, insulation refractories excellent,.
      It is widely used in lightweight castable production and oil drilling.
      The chemical composition of cenosphere silica and three to two aluminum oxide based,
      It has fine grain, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation, flame retardant insulation and other properties, is widely used in one of the refractory raw material industry.

Please inform us if you demand more details.

and other details as:
   Cenospheres have been used for more than 30 years to improve the qualities of a multitude of manufactured products. Some desirable traits of cenospheres are their excellent thermal insulation, controllable density for buoyancy, high melting point, chemical and flame retardance, density management and low absorption level.
