What is Ammonium Oxalate?
Ammonium Oxalate is the ammonium salt of oxalic acid, available as a white crystalline powder that is moderately soluble in water. It is valued primarily for its chelating properties — its ability to bind strongly with metal ions, particularly calcium and iron — which makes it effective in rust removal, metal surface cleaning, and certain analytical chemistry applications where selective metal ion precipitation or complexation is required.
Polychem Industries supplies Ammonium Oxalate to metal finishing companies, rust remover product manufacturers, analytical laboratories, and ceramic industry customers across India and internationally. Its strong chelating action with iron and calcium ions makes it particularly valuable in rust and scale removal formulations, as well as in quantitative analytical chemistry procedures.

Applications & Uses
Rust & Scale Removal
Used in rust remover and metal cleaning formulations due to its ability to form soluble complexes with iron oxide (rust), helping dissolve and remove rust deposits from metal surfaces without aggressive mechanical abrasion.
Metal Surface Cleaning & Polishing
Used in metal cleaning and polishing compound formulations, particularly for stainless steel and other metal surfaces, where its mild chelating action helps remove surface oxidation and restore a clean, polished appearance.
Analytical Chemistry
Used in quantitative analytical chemistry as a precipitating agent for calcium determination, taking advantage of the formation of insoluble calcium oxalate, which is a classical analytical technique for calcium quantification.
Ceramics & Glass Polishing
Used in certain ceramic and glass polishing formulations, where its mild abrasive and chelating properties contribute to achieving a clean, polished surface finish on these materials.
Photography & Developing
Historically used in certain photographic developing and toning processes, taking advantage of its reducing and complexing chemical properties in specialised photographic applications.
Wood & Stone Cleaning
Used in certain wood bleaching and stone cleaning formulations, particularly for removing iron-based stains and discoloration from these porous materials.
