High Quality Cenospheres Suppliers in China | Hollow Ceramic Microspheres Factory
Cenospheres are high-performance, lightweight, inert, and hollow non-metallic spherical materials. Primarily composed of silica (SiO2) and alumina (Al2O3), these hollow ceramic microspheres possess chemical properties similar to glass and ceramics, making them an ideal choice for advanced industrial fillers.
Engineered for versatility, Cenospheres combine a unique spherical morphology with high compressive strength and exceptional thermal and sound insulation. They serve as a superior replacement for traditional mineral fillers across a wide array of demanding applications, from aerospace coatings to heavy-duty construction materials.

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 improve the physical and thermal properties of coatings, plastics, and construction materials.
Q: How do Cenospheres improve the performance of industrial paints?
They provide non-slip textures, enhance corrosion resistance, and offer thermal insulation and anti-condensation properties, making them ideal for marine and industrial environments.
Q: Can Cenospheres replace other mineral fillers in plastics?
Yes, they can replace various mineral fillers in BMC, SMC, and injection molding. They reduce the end product weight and resin demand while improving flowability during manufacturing.
Q: What is the difference between different grades like TX and TST-100?
The grades differ primarily in particle size, bulk density, and color. For example, TST-100 offers a specific true density (0.8-0.95g/cc) and an off-white color, whereas TX is light grey with a higher bulk density.
Q: Why is the "Floating Rate" important for hollow ceramic spheres?
The floating rate indicates the percentage of truly hollow spheres. A higher floating rate (up to 95%) ensures maximum weight reduction and superior insulation properties in the final application.
Q: Are Cenospheres suitable for aerospace and energy sector applications?
Absolutely. Due to their high strength-to-weight ratio and chemical inertness, they are widely used in aerospace composites and oil well cements for drilling operations.
