铝硅酸盐微球 (cenospheres light fraction of fly ash, bottom ash microspheres , microspheres energy ashes) are hollow beads with a size range of 20-500 microns (most often, 100 – 250 microns) and a by-product of coal burning power plants.
Compared to irregular-shaped and partially-spherical fillers, the 100% spherical shape of Ceramic Microspheres, provides improved processing and performance.Being inert it is not affected by solvents, water, acids or alkalis. They are 75% lighter than other minerals currently used as a filler or extender.
该产品独特的品质组合，如近乎理想的球形、低堆积密度、高机械强度、热稳定性和化学惰性，提供了以下广泛的应用：
1.建筑：超轻混凝土，绝缘石膏和砌筑砂浆以及其他类型的干混料，设备屋面和立面结构、地板的隔热隔音覆盖，以及地板隔热的制备。
2.Paints Coating: Cenospheres are special additives that both chemists and formulators in the paints and coatings industry are using to enhance their products. A sphere has the lowest surface area of any shape.As a result, these hollow ceramic microspheres reduce resin demand and increase volume loading capacity.
3.Oil Field: oil well cements, drilling muds, grinding materials, explosives.
空心微珠在油田固井中的应用已有相当长一段时间。在固井作业中，空心微珠可降低泥浆密度而不增加含水量。这反过来又为水泥提供了更好的抗压强度。
4.Ceramics: Refractories, Castables, Tile, Fire Bricks, Aluminium Cement, Insulating materials, Coatings.
5.Plastics: Cenospheres are an excellent lightweight filler for plastics and continue to grow in popularity and use. Not only do they reduce the cost of the composite but Cenospheres often impart performance improvements that might otherwise not have been achieved. It is used in all types of Moulding, Nylon, Low Density Polyethylene and Polypropylene.
6.Automotive: composites, engine parts, sound proofing materials, undercoatings.
