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.
Cenospheres are low density, very useful in the manufacturing of plastics, sealants, automotive parts and under coatings, and in applications as diverse as aerospace, sound dampening, and putties where lightweight material is key. Using lower density materials in the manufacturing of construction materials is becoming more popular. The lightweight, yet strong nature of the cenospheres adds versatility, strength, lowered shrinkage and sag levels.
