Alumina Transparent Ceramic

This ceramic has a bending strength of over 350MPa and a thermal expansion coefficient of (6.5~8.5)×10⁻⁶/°C, making it suitable for high-pressure sodium lamp luminescent tubes, microwave integrated circuit substrates, and dental braces. The preparation process includes isostatic pressing and atmospheric sintering, with key technologies involving the optimization of grain boundary structure and surface polishing to a finish of 11 to 13. Professor Zhao Zhe's team has achieved high-precision molding through digital light processing stereolithography technology, expanding the application range of this material.
