Phosphoric Acid – Industrial Grade 85% H₃PO₄ Bulk Supply

Phosphoric Acid (H₃PO₄) is a versatile inorganic mineral acid primarily used across the agriculture, food, pharmaceutical, and industrial sectors. Cavin Resource offers premium-grade phosphoric acid in both food and industrial grades, with purity levels ranging from 75% to 85% depending on the application.

Our phosphoric acid is manufactured using either wet-process (from phosphate rock) or thermal-process (via phosphorus combustion), ensuring tailored specifications based on client demand. We deliver in IBC tanks, drums, or ISO tanks, supporting both small-scale and bulk B2B supply needs.

With a strong global logistics network, we ensure fast delivery and strict compliance with REACH, ISO, and SGS certifications.

⚙️ Production Method

1. Wet Process

• Sulfuric acid reacts with phosphate rock

• Resulting phosphoric acid is purified and concentrated

• Commonly used for fertilizer and industrial applications

2. Thermal Process

• Elemental phosphorus is combusted to form phosphorus pentoxide

• Absorbed in water to yield high-purity phosphoric acid

• Suitable for food-grade and high-purity uses
