Product Overview

• Phosphoric Acid is a strong, non-oxidizing mineral acid widely used across fertilizer, food processing, metal treatment, and general chemical manufacturing industries. It appears as a clear, colorless, syrupy liquid, fully miscible with water in all proportions. Procorbay International supplies Phosphoric Acid across food-grade and industrial/technical-grade specifications, serving as a foundational raw material for phosphate fertilizer production, a food-grade acidulant, and a metal surface treatment (phosphating/rust-proofing) agent.
• Phosphoric Acid is commercially manufactured either through the wet process (reacting phosphate rock with sulfuric acid, yielding technical/fertilizer-grade material) or through the thermal process (combustion of elemental phosphorus followed by hydration, yielding higher-purity food and industrial-grade material). Procorbay sources Phosphoric Acid from established phosphate chemical manufacturers, offering both food-grade and technical-grade specifications to serve differing buyer purity requirements.
• Industrially, Phosphoric Acid's largest application by volume is as the foundational raw material for phosphate fertilizer production (including DAP, MAP, and various NPK formulations), reflecting its critical role in global agricultural nutrient supply chains. In food processing, food-grade Phosphoric Acid serves as an acidulant and flavoring agent, notably in cola-type soft drinks, as well as a processing aid in various food applications. In metal treatment, it functions as a phosphating agent for rust-proofing and paint-adhesion surface preparation on steel components, and as a rust remover and cleaning agent. It also serves as a raw material in the production of various phosphate salts, catalysts, and specialty chemical compounds used across water treatment and industrial processing applications.
• Given its foundational role across fertilizer production and its broad cross-industry relevance, Procorbay maintains consistent, multi-grade Phosphoric Acid supply to serve fertilizer, food, metal treatment, and chemical manufacturing buyers.
