Product Description

Product Description

 

 

Cenosphere  is an excellent thermal insulation refractory material and widely used in the production of lightweight castables and oil drilling.
It has many characteristics such as fine particles, hollow, light weight, high strength, wear resistance, high temperature resistance, thermal insulation, insulation and flame retardant, and is one of the raw materials widely used in the refractory industry.

Like fly ash, cenospheres are naturally occurring by-products of the burning process at coal-fired power plants. Unlike fly ash though, cenospheres are lightweight, inert, hollow spheres comprised largely of silica and alumina and filled with air or gases. 

Since they are inert, they are not considered a pozzolan. The color of cenospheres varies from gray to almost white and their density is about 0.4-0.8 g/cm3 , which gives them a great buoyancy. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.

Our Advantages

Excellent performance and use of Cenosphere

1. High refractoriness:

Cenosphere have extremely high refractoriness, generally reaching 1600-1700 degrees Celsius, making them an excellent high-performance refractory material.

2. Lightweight, thermal insulation:

Cenosphere is not only light in weight (bulk density 250-450 kg/m3), but also excellent in thermal insulation (thermal conductivity at room temperature 0.05-0.1). 

3. High hardness and high strength:

Because Cenosphere is a hard glass body formed from the silicon-aluminum oxide mineral phase (quartz and mullite), the hardness can reach Mohs 6-7, the static pressure strength is as high as 70-140MPa, and the true density is 2.10-2.20 g/cm3. Therefore, Cenosphere has high strength.


4. Fine particle size and large specific surface area:

The natural particle size of Cenosphere is 1-250 microns. The specific surface area is 300-360g/cm2, which is similar to cement.
Therefore, Cenosphere does not need to be ground and can be used directly.


5. Excellent electrical insulation:

Cenosphere is an excellent insulating material and does not conduct electricity.
