High Quality Aluminosilicate Microspheres Cenospheres China Factory Suppliers
Aluminosilicate Microspheres, commonly known as Cenospheres, are high-performance, lightweight, inert hollow ceramic spheres primarily composed of silica (SiO2) and alumina (Al2O3). These nonmetallic spherical materials offer a unique structural composition similar to glass and ceramics, making them an indispensable additive for industries requiring low density and high thermal stability.
Engineered for versatility, these hollow microspheres provide exceptional characteristics including low thermal conductivity, high heat resistance up to 1700°C, and superior electrical insulation. From aerospace components to specialized construction materials, our Cenospheres deliver a cost-effective solution for reducing weight without compromising structural integrity or chemical stability.

Frequently Asked Questions
Q: What are Cenospheres and how are they used in non-metallic mineral manufacturing?
Cenospheres are hollow ceramic microspheres composed of silica and alumina. In the non-metallic mineral industry, they are used as lightweight fillers to reduce density and improve thermal insulation in composites, cements, and coatings.
Q: Which grade of Cenosphere should I choose for high-precision coatings?
For high-precision coatings, smaller particle sizes such as TS-100 or TS-150 (100-150 microns) are recommended to ensure a smooth finish and uniform distribution.
Q: Can Aluminosilicate Microspheres withstand extreme fire conditions?
Yes, Cenospheres are exceptionally fire-resistant, with a fire-resistant degree ranging between 1600°C and 1700°C, making them ideal for fire-retardant paints and aerospace materials.
Q: How do Cenospheres improve the properties of concrete in construction?
They create ultra-light concrete by replacing heavier aggregates, which improves thermal and sound insulation while reducing the dead load of the structure.
Q: Are these microspheres chemically compatible with epoxy and polymer resins?
Yes, because they are chemically inert, they integrate seamlessly into various polymeric materials without causing adverse chemical reactions.
Q: What is the "Floating Rate" and why is it important?
The floating rate (typically 93-95% min) indicates the percentage of hollow spheres versus solid particles. A higher floating rate ensures lower density and better buoyancy for applications like life jackets and buoys.
