Lightweight Cenosphere Fillers from China - Quality Suppliers & Factory for Casting and Plastic Applications
Cenospheres Production and our factory
The process of burning coal in thermal power plants produces fly ash containing ceramic particles made largely of alumina and silica. They are produced at temperatures of 1,500 to 1,750 °C (2,730 to 3,180 °F) through complicated chemical and physical transformation. Their chemical composition and structure varies considerably depending on the composition of coal that generated them.
Our cenosphere factory established in 1980, manufacturing around 4,000tons yearly. During the production, we withdraw and test the sample every half an hour, control the size distribution, true density, bulk density, whiteness and floating ratio very strictly. We ship our Cenosphere to Japan, Korea, Southeast Asia, America and South America etc markets, mainly used for Foundry & Casting industry, Plastic filter, Insulation material and Refractory materials. Based on professional production, timely delivery and strict quality control, we are confident in providing you with the most suitable Cenosphere.

Frequently Asked Questions
What are Cenospheres and how are they produced?
Cenospheres are lightweight, ceramic particles made largely of alumina and silica. They are produced as a byproduct of burning coal in thermal power plants at temperatures of 1,500 to 1,750 °C (2,730 to 3,180 °F) through complicated chemical and physical transformations.
What is your factory's production capacity and experience?
Established in 1980, our factory has decades of manufacturing experience, producing approximately 4,000 tons of Cenospheres annually.
How do you guarantee the quality of your Cenospheres?
We withdraw and test samples every half an hour during production. We strictly control key metrics including size distribution, true density, bulk density, whiteness, and floating ratio (which is maintained at 90-96%).
What are the primary applications and markets for your products?
Our products are exported to Japan, Korea, Southeast Asia, America, and South America. They are primarily used in the Foundry & Casting industry, Plastic filters, Insulation materials, and Refractory materials.
What packaging and container shipping options are available?
We offer packaging in 25kg, 500kg, 550kg, and 600kg bags. For shipping, we can load 10-12 Mt per 20'GP container and 22-26 Mt per 40'HQ container.
