Cenosphere

Product introduce:

Made up of silica, iron and alumina, cenospheres have a size range from 1 to 500 microns with an average compressive strength of 3000+ psi. Colors range from white to dark gray. They are also referred to as microspheres, hollow spheres, hollow ceramic microspheres, micro-balloons, or glass beads..

Cenosphere is able to float on the surface of fly ash hollow ball, pale, thin-walled hollow, very light weight, bulk density 720kg/m3 (heavy), 418.8kg/m3 (light), particle size of about 0.1 mm , closed and smooth surface, thermal conductivity is small, refractoriness ≥ 1610 °C, is an excellent insulating refractory castable used in the production and light oil drilling areas. The chemical composition of floating beads of silica and alumina-based, with fine particles, hollow, light weight, high strength, wear resistance, high temperature, heat insulation, fire-retardant insulation and other functions, now widely used in One of refractory materials

2. Cenospheres are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion.Cenospheres are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion during the generation of electric power. Small and hollow, micropheres are used as fillers or functional extenders in the manufacture of plastics, paints, resins; light weight aggregates for cement, ceramics and other construction products. Because cenospheres often replace mined materials, they can significantly lower production costs. Simultaneously, cenospheres can benefit finished product properties by increasing durability and better sound proofing. Too, as material recycled from flyash, cenospheres are environmentally friendly and help to preserve natural virgin fillers.
As a portion of the flyash generated in coal combustion, cenospheres are recycled from the waste stream. They are made up of inert silica, iron and alumina. Cenospheres have a size range from 1 to 300 microns with an average compressive strength of 3000+ psi.. Colors range from white to dark gray. They are also referred to as microspheres, hollow spheres, hollow ceramic microspheres, microballoons, or glass beads.
The spherical shape of cenospheres improves flowability in most applications and provides a more even distribution of the filler material. The natural properties of cenospheres make it possible to use them either in dry or wet slurry form. Cenospheres are easy to handle and provide a low surface area-to-volume ratio. Due to their inert properties, they are not affected by solvents, water, acids, or alkalis, cenospheres are 75% lighter than other minerals currently used as a filler or extender and are 30% lighter than..

Applications:

Cenosphere applications offer many benefits over mined materials,primarily cost and weight reduction. Of their many uses, microspheresare used as light weight aggregate in oil well cements, sound proofing,thermal insulation, interior and exterior paints, injection molding ofplastics,automotive brake linings, and are even used by NASA in the nose of the Space Shuttle.
Desirable properties include: controllable density for buoyancy, improved flow, excellent thermal insulation, light weight, and high strength. Environmentally friendly and 100% they aid not only the coal fired power plants control their pollution, but make their use earth conscious.
