Frequently Asked Questions (FAQ)
Cenospheres are lightweight, hollow ceramic particles made largely of alumina and silica. They are produced as a byproduct of coal combustion in thermal power plants at temperatures ranging from 1,500 to 1,750 °C (2,730 to 3,180 °F) through complex chemical and physical transformations.
Our factory was established in 1980 and has an annual manufacturing capacity of approximately 4,000 tons. We perform strict quality control by withdrawing and testing samples every half hour.
Our products are widely 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.
We offer sizes in 20, 40, 60, 80, 100, and 150 mesh. The bulk density ranges from 0.35 to 0.46 g/cm³, true densities are 0.75, 0.85, 0.95, and 1.05, the floating ratio is 90-96%, and the melting point is 1500-1650℃.
Our Cenospheres consist primarily of SiO2 (57 – 60%) and Al2O3 (30 – 33%), with smaller percentages of 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 a loss on ignition (LOI) of 0.85 – 1.15%.
We offer packaging options 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.
