TRUNNANO Launches Next-Generation Spherical Silica SiO2 Powder, Leading the Way in Materials Technology Innovation
LUOYANG, China, Oct. 20, 2025 (GLOBE NEWSWIRE) -- TRUNNANO, a leading global nanomaterials manufacturer, officially announced that its R&D team has achieved a breakthrough in the preparation technology of spherical silica SiO2 powder, successfully launching a new generation of high-performance spherical silica SiO2 powder. This marks a technological leap for TRUNNANO in the field of fine chemicals and will provide superior material solutions for multiple key industries worldwide.
Spherical silica SiO2, a fundamental functional material, is widely used in electronic packaging, composite materials, coatings, adhesives, and advanced ceramics due to its high purity, excellent chemical stability, and tunable physical properties. However, traditional production processes have long faced challenges in controlling particle sphericity, surface smoothness, and batch consistency. TRUNNANO's newly released next-generation spherical silica SiO2 powder successfully overcomes these long-standing technical bottlenecks through its unique synthesis and refining processes.

Technical Parameter of Spherical quartz powder Spherical SiO2
Technical Breakthrough 1 - Ultimate Sphericity and Smooth Surface
This new technology ensures that each silica particle exhibits a highly perfect spherical structure with an exceptionally smooth surface. This near-ideal geometry significantly reduces inter-particle friction and stress concentration, enabling denser packing and more uniform dispersion in composite systems.
Technical Breakthrough 2 - Customizable Surface Properties
Based on a deep understanding of surface chemistry, TRUNNANO's technology allows for precise surface modification of spherical silica SiO2 powders. Customers can obtain products with varying surface activity and compatibility based on their specific application requirements, making them easier to integrate into various complex application systems and achieve optimal performance.
