Latest Patents

The listed patent, “Copper-tin-nickel brazing material prepared by alloys recycled from E-waste, preparation method therefor, and system thereof,” describes a process for converting crude copper-tin-iron-nickel alloy recovered from electronic waste into brazing material.

The method begins by placing nano-silicon dioxide in a crucible and adding the crude alloy. Heating melts the alloy, allowing zinc and lead to react with the silicon dioxide and form floating slag. Refining gas is then introduced at the bottom of the molten metal to help remove impurities and gases associated with lead, iron, sulfur, and oxygen. Directional solidification concentrates iron and antimony at one end for removal, producing a copper-based intermediate alloy that is subsequently smelted and powdered.

Career Highlights

Yang’s listed invention addresses the recovery and processing of metals from electronic waste. By describing steps for impurity removal and alloy refinement, the patent presents a route for preparing copper-based brazing material from recycled feedstock.
