Latest Patents

Quan Yang holds a patent for an innovative braze and brazing process designed for hermetic sealing between ceramic and metal components in high-temperature oxidizing or reducing atmospheres. The patent describes a superior braze material, which is based on a metal oxide-noble metal mixture, typically Ag-CuO. This material is enhanced with a small amount of metal oxide and/or metals such as TiO, AlO, YSZ, Al, and Pd, which improve wettability and joint strength. The braze filler materials can be prepared in the form of paste or thin foil through a high-energy cryogenic ball milling process. This method allows for finer braze particles, resulting in a more evenly dispersed braze layer between the ceramic substrate and metallic parts.
