DENKA’s fused silica leverages a long history of expertise in ceramics technology to bring added value to customers. Our fused silica is produced from molten quartz, which is then formed into microspheres by means of precise modification of surface tension. Our unique know-how enables us to finely control particle size and sphericity for optimal particle distribution.
DENKA’s fused silica boasts high sphericity, enabling advantages such as improved flowability, higher loading quantity, and improved wear resistance for in-resin filler applications. DENKA’s fused silica has developed a considerable track record of excellent performance as a filler for semiconductor sealing epoxies, and low uranium (low alpha) grades are also available for memory applications.
