Cenosphere(Expanded Mineral Materials Containing Alumina and Silica) is a light weight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coal  combustion at thermal power plants. The color varies from gray to almost white and their den sity is about 0.6–0.9 g/cm³, all these property give it a widely application for insulation,refractory,oil drilling,coating,construction use. Cenospheres In Heat-Insulating Refractory Concretes Microspheres, due to their fire resistance and high heat-insulating properties, are used in the production of thermal insulation materials. The high temperature of microsphere shell softening allows, with the appropriate selection of the binder, creating refractory coating and insulating materials for industrial equipment. Cenospheres Color: gray Particle size: Based on customer requirements Shape: hollow microspheres Material: glass, nontoxic, odorless, non corrosive Silica: 50% ~ 65% Alumina: 27% ~ 35% Fe2o3：2%~3% MgO: 0.8% ~ 1.2% Silica: 0.1% ~ 0.2% Cao: 0.2% ~ 0.4% MgO: 0.8% ~ 1.2% Potash: 0.5% ~ 1.1% Sodium oxide: 0.3% ~ 0.9% Fire resistance: ≥1610 ℃ Floating Rate:≥95% Moisture content:≤1% Our usually packing way： 25kg/pp bag or 500~600kg/ bag Usage : 1.Cementing: Oil Drilling Mud & Chemcials,Light Cement Boards,Other Cementious Mixes. 2.Plastics: All types of Moulding,Nylon,Low Density Poluethylene and Polypropylene. 3.Construction: Speciality Cements and Mortars,Roofing Materials.Acoustic Panels,Coatings. 4.Automobiles: Fabrication of composite polymeric putties. 5.Ceramics: Refratories,Tiles,Fire Bricks. 6.Paints and Coating: ink,bond,vehicle putty, insulating, antiseptic, fireproof paints. 7.Space or Military: explosives,invisible paints for planes,ships and even soldiers,heat and compression insulating compounds,deep-water submarine.
