According to news from the financial industry on August 25, 2024, Tianyancha’s intellectual property information shows that Hunan Meicheng Ceramics Technology Co., Ltd. has obtained a project called “An Alumina Ceramic Brazing Process”, with the authorization announcement number CN117900582B, and the application The date is February 2024.

The patent summary shows that the present invention relates to the field of brazing technology, specifically an alumina ceramic brazing process. REMn2O5, glass powder, aluminum fluoride and binder are mixed and stirred evenly to obtain a solder paste, which is added to the alumina ceramics. The solder paste is printed on the ceramic to form a "sandwich" structure of alumina ceramic-solder paste-alumina ceramic, and then vacuum high-temperature brazing is performed. The shear strength of the welded joint obtained by the process of the present invention reaches more than 100MPa, ensuring It improves the reliability of the alumina ceramic connection. The solder paste achieves good infiltration and flow between the alumina ceramics, filling the gaps between the alumina ceramics. The joints formed are uniform, and no slag inclusions or pores can be seen with the naked eye. and other defects.
