Hollow microsphere is one kind of coal ash hollow ball which can floating on the water. Pale color, thin-walled hollow, very light weight. The volume weight range from **0 to **0 kg/m3, Particle size is about 0.1 mm. its Surface closed and smooth, Thermal conductivity small, refractory degree equial or greager than ***0°C, is excellent insulation refractory materials, widely used in light pouring material production and oil drilling and many other aspects.
The major chemical compositions of Hollow microsphere are silica and the aluminum oxide based, It has the functions of fine particles, hollow, light weight,high strength, wear-resistant, thermal insulation, fire-retardant insulation and many other features.
