Product Description

Product Description

SEPPE Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and their bulk density is about 0.4-0.8 g/cm3, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.

Advantages&Applications

1. High refractoriness:

Cenosphere (Main SiO2 and Al2O3)have extremely high refractoriness, generally reaching 1600-1700 degrees Celsius, making it an excellent high-performance refractory material.

2. Lightweight, thermal insulation:
Cenosphere has thin and hollow walls and a semi-vacuum in the cavity. There is only a trace amount of gas (N2, H2, CO2, etc.), and the heat conduction is extremely slow and minimal.

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.

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.

5. Excellent electrical insulation:
Cenosphere's resistance increases with the increase of temperature. This advantage is not available in other insulating materials.

Packaging & Shipping

Packing: 600kg big jumbo bags with pallets, 2 bags on 1 pallet.
