Our company's Ceramic Encapsulation Tube Research Center was established in September 2021, focusing on the research and production of various ceramic encapsulation shells. The department currently possesses ceramic tape casting technology, multi-layer ceramic processing technology, multi-layer ceramic sintering and surface treatment technology. As the material for the third-generation vacuum device tube shells, ceramic tubes and shells can be widely used in laser devices, microwave radio frequency, optical communication, power devices, hybrid integrated circuit devices, and other fields.
