Lightweight Cenosphere Fillers from China Suppliers - High-Quality Factory Products for Casting and Plastics
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 ceramic particles made largely of alumina and silica. They are produced during the burning of 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 transformation.
What is your factory's annual production capacity and experience?
Our factory was established in 1980 and manufactures around 4,000 tons of Cenospheres yearly. We maintain strict quality control by withdrawing and testing samples every half hour during production.
What sizes and density ranges of Cenospheres do you offer?
We offer sizes of 20mesh, 40mesh, 60mesh, 80mesh, 100mesh, and 150mesh. The bulk density ranges from 0.35 to 0.46g/cm³, and true densities are available at 0.75, 0.85, 0.95, and 1.05.
What is the typical chemical composition of your Cenospheres?
Our Cenospheres consist of SiO2 (57 – 60%), Al2O3 (30 – 33%), Fe2O3 (2.4– 3.2%), K2O (1.1 – 1.3%), CaO (0.88 – 1.2%), TiO2 (0.8 – 1.15%), H2O (0.35 – 0.5%), and LOI (0.85 – 1.15%).
What are the main industrial applications for Cenospheres?
They are mainly used in the Foundry & Casting industry, Plastic filters, Insulation materials, and Refractory materials. They also serve as plastic additives, lightweight castables, high-grade paving, oil drilling materials, high-temperature/voltage insulators, and metallurgy casting.
What packaging and shipping options are available?
We offer packaging in 25kg, 500kg, 550kg, and 600kg bags. The shipping quantities are 10-12Mt for a 20'GP container and 22-26Mt for a 40'HQ container.
