Industrial Applications & Benefits
High-Efficiency Auxiliary for Rare Metal Separation
In the hydrometallurgy of rare metals like tungsten and molybdenum, thiourea acts as a selective precipitating agent that effectively separates associated metal impurities, enhancing target metal purity and recovery rates while optimizing the overall smelting process.
Eco-Friendly Etching & Polishing Agent
In semiconductor and precision equipment manufacturing, thiourea-based formulations enable micron-level etching and chemical polishing of metals like copper and silver. The process is mild and controllable, with waste liquids that are easier to treat, aligning with green manufacturing standards.
High-Performance Corrosion Inhibition Synergist
In industrial circulating water systems and acid pickling processes, thiourea works synergistically with conventional corrosion inhibitors to significantly enhance protection for multi-metal systems (including carbon steel and copper alloys), extending equipment service life.
