Premium Cenospheres Hollow Ceramic Microspheres China Factory Suppliers
Our high-performance Cenospheres (Hollow Ceramic Microspheres) are premium silica-alumina spheres recovered from high-quality fly ash produced at thermoelectric power stations. These lightweight, spherical particles offer an exceptional combination of thermal insulation and structural strength, providing a cost-effective alternative to synthetically produced microspheres without compromising on technical performance.
Engineered for versatility, these cenospheres feature a smooth surface and diameters ranging from 20 to 500 microns. By incorporating these hollow spheres into your industrial formulations, you can significantly reduce raw material costs, enhance flowability, and lower the overall weight of end products while maintaining superior resistance to resin absorption.

Frequently Asked Questions
Q: What are cenospheres used for in the non-metallic mineral industry?
Cenospheres are used as lightweight fillers and additives in various applications including foundry resins, thermal insulation coatings, plastics, and automotive components to reduce weight and improve thermal properties.
Q: How do cenospheres help in reducing foundry raw material costs?
Because cenospheres are recovered from fly ash, they are significantly cheaper than synthetically produced hollow ceramic spheres while offering similar chemical and physical properties.
Q: What is the typical particle size range for your Cenospheres?
Our cenospheres generally range from 20 to 500 microns. We offer standard grades like 20-70 mesh and customized sizes such as 40, 50, 80, 100, and 150 mesh.
Q: Why is a high floating rate important for hollow ceramic microspheres?
A high floating rate (e.g., >95%) indicates a high percentage of intact hollow spheres, which is critical for ensuring low bulk density and superior insulation performance.
Q: Can cenospheres be used in construction and building materials?
Yes, they are widely used in building and construction to create lightweight concrete, thermal insulation plasters, and high-performance mortars.
Q: What packaging options are available for bulk orders?
We provide 20kg and 25kg kraft paper bags for small to medium orders, and 500kg or 600kg big bags for industrial bulk shipments, or customized packaging upon request.
