Why Choose Industrial Grade Phosphoric Acid?
Superior Purity Standards
Meets GB/T2091-2008 international standards with rigorous quality control. Each batch is tested for H₃PO₄ content, heavy metals, and contaminants to ensure consistent industrial-grade performance.
Cost-Effective Solution
Industrial-grade phosphoric acid offers exceptional value without compromising on quality. Bulk packaging options (35kg to 1650kg) reduce per-unit costs and minimize packaging waste.
Stable & Long Shelf Life
Phosphoric acid is highly stable under normal storage conditions. Its non-volatile nature means minimal evaporation, and proper storage in sealed containers ensures multi-year shelf life without degradation.
Regulatory Compliance
Our phosphoric acid complies with international regulations including REACH certification. Comprehensive documentation and safety data sheets are provided for all shipments.
Description
Chemical Appearance & Physical Properties:
Phosphoric Acid 85% Industrial Grade is a clear, colorless to slightly yellow, and odorless syrupy liquid. It is a non-volatile, non-oxidizing mineral acid that is highly soluble in water. While it is a strong acid with a pH of approximately 1.5 in aqueous solution, it is safer to handle than many other mineral acids like hydrochloric acid or sulfuric acid, making it a preferred choice for various industrial processes. The 85% concentration represents the optimal balance between reactivity and stability for industrial applications.
Our phosphoric acid maintains exceptional purity levels, with minimal impurities including iron, arsenic, and heavy metals. This high-purity formulation ensures consistent performance across diverse industrial applications and minimizes contamination risks in sensitive processes.

Key Chemical Characteristics of Phosphoric Acid:
- Molecular Formula: H₃PO₄ — A triprotic weak acid with three ionizable hydrogen atoms, enabling multiple reaction pathways in industrial chemistry.
- Density & Viscosity: At 85% concentration, phosphoric acid has a density of approximately 1.7 g/cm³, providing excellent handling characteristics and precise dosing in automated systems.
- Non-Oxidizing Nature: Unlike nitric acid, phosphoric acid does not oxidize most metals, making it ideal for metal surface treatment without causing unwanted corrosion.
- Hygroscopic Properties: Phosphoric acid readily absorbs moisture, which is advantageous in drying applications and humidity control in industrial processes.
- Thermal Stability: Maintains chemical integrity at elevated temperatures, making it suitable for high-temperature industrial processes and thermal synthesis reactions.
