Product Summary

Potassium Metaphosphate is supplied as a high-purity phosphorus-potassium compound. The measured purity is 99.99%, with iron at 1.6 ppm and cobalt, chromium, titanium, copper, manganese, nickel, and vanadium each below 1 ppm. It is non-hygroscopic and non-caking, supports slow-release potassium in soil, and serves water treatment, detergent, rust-prevention, and high-temperature lubricant applications.

Key Features

• 99.99% measured purity. The stated grade is 99.95% or above, with measured values up to 99.99%, supporting stable performance and reducing impurity-related side reactions.
• Controlled metal impurities. Fe is 1.6 ppm; Co, Cr, Ti, Cu, Mn, Ni, and V are each below 1 ppm, with metal impurities controlled within 5 ppm.
• Slow-release phosphorus and potassium. Provides both nutrients and releases potassium slowly in soil for longer crop feeding and lower fertilizer dosage.
• Non-hygroscopic and non-caking. Supports convenient storage and application without caking.
• Multifunctional industrial performance. Works as a scale and corrosion inhibitor in boilers and circulating cooling water, a detergent builder and rust inhibitor, and a high-temperature lubricant additive.

Models and Options

This high-purity grade is defined by the specification table above. Bulk orders support flexible packaging solutions and logistics coordination; discuss your required pack size with the sales team.

Materials and Structure

Potassium metaphosphate is the product material. The supplied data confirm a controlled metal impurity profile, 0.35% weight loss on burning, and non-hygroscopic, non-caking behavior. These characteristics support stable storage and handling in fertilizer, water treatment, cleaning, and lubricant applications.

Applications

• Agriculture: efficient phosphorus-potassium compound fertilizer for corn, sugar beet, soybean, fruit trees, and other crops with high phosphorus and potassium demand.
• Water treatment: scale inhibitor and corrosion inhibitor in boilers and circulating cooling water systems.
• Detergents and cleaning: water softener, detergent builder, and rust inhibitor that helps prevent redeposition of dirt.
• Metal surface treatment: forms a protective film for rust prevention.
• Lubricants: additive for high-temperature lubricants used in mechanical equipment and automotive parts.

Customization

Customers can verify product effects in their own systems through sample testing. The company assists with application data analysis and usage recommendations, supports flexible packaging for bulk orders, coordinates logistics, and follows up regularly to track usage.
