Pharmaceutical Synthesis Oxalic Acid Intermediate for API Manufacturing

Oxalic Acid Dihydrate (Industrial Grade): Specialty Materials & Process Optimization Applications

1. Dispersing Agent for Ultrafine Metal Powder Preparation
   In the production of ultrafine copper powder, nickel powder, and other metal powders through atomization and reduction methods, oxalic acid dihydrate serves as a surface modifier. It prevents particle agglomeration, controls powder particle size distribution, and meets high-end requirements in conductive pastes and powder metallurgy applications.

2. Corrosion Inhibition Synergist in Chemical Equipment Pickling
   In chemical equipment descaling through acid cleaning, oxalic acid dihydrate works synergistically with conventional corrosion inhibitors, enhancing protection for specialty metals such as stainless steel and titanium alloys. It avoids over-corrosion risks and ensures safe cleaning operations.

3. Functional Ceramic Additive
   In the preparation of functional ceramics such as piezoelectric ceramics and dielectric ceramics, oxalic acid dihydrate acts as a sintering aid and grain refiner. It lowers sintering temperatures, improves ceramic density and electrical properties, and enhances product consistency.

4. Biofilm Remover for Industrial Circulating Water Systems
   In cooling water systems, oxalic acid dihydrate assists in removing biofilms and microbial slime from pipeline interiors. When used with biocides, it enhances biofilm detachment effectiveness and maintains system heat transfer efficiency.
