CAS 13573-12-1
99.99% Purity Low Impurity Flame Retardant Magnesium Metaphosphate
High-purity Magnesium Metaphosphate for flame retardant materials, catalysts, phosphate fertilizer and humidity-control applications.
URL slug: magnesium-metaphosphate-99-99-purity
Product Summary
Magnesium Metaphosphate (CAS 13573-12-1) is supplied with 99.99% purity, exceeding the stated 99.95% standard requirement. Seven metal elements, including cobalt, chromium, titanium, copper, manganese, nickel and vanadium, are each below 1 ppm, while iron is 2.6 ppm against a 5 ppm control standard. Loss on weight on burning is 0.42%, better than the 0.5% requirement.
This impurity profile supports flame retardant materials, catalysts, phosphate fertilizer production and humidity-control applications where raw material purity matters. The product is strictly tested before leaving the factory, and packaging is available in plastic woven bags, aluminum foil bags and fiber drums.
Key Features
- 99.99% purity: exceeds the stated 99.95% standard requirement, giving formulators more active ingredient and less impurity interference.
- Low metal impurities: Co, Cr, Ti, Cu, Mn, Ni and V are each below 1 ppm; Fe is 2.6 ppm versus a 5 ppm control standard.
- 0.42% loss on ignition: better than the stated 0.5% requirement for consistent processing.
- Flame retardant function: works in high-temperature environments and disperses evenly in plastic, coating and textile substrates for consistent flame retardant effects.
- Multiple application routes: usable as a desiccant, a phosphorus source for phosphate fertilizer and a catalyst component.
- Packaging and storage: plastic woven bags, aluminum foil bags or fiber drums; store in a ventilated, low-temperature, dry warehouse separate from oxidants and food additives.

Applications
Flame Retardant Materials
For plastics, coatings and textiles. In plastics it helps materials reach corresponding fire resistance ratings; in fireproof coatings it forms a denser intumescent insulating layer; in textiles it provides lasting flame retardancy and water washing resistance.
Desiccant
Stable moisture absorption for electronic components, precision instruments, pharmaceuticals and food packaging where humidity control is needed.
Phosphate Fertilizer
Acts as a phosphorus source absorbable by crops, helping improve soil fertility and promote crop growth.
Catalyst Component
Assists specific chemical reactions and improves reaction efficiency.
Customization
Packaging can be selected from plastic woven bags, aluminum foil bags and fiber drums to meet different transportation and storage needs. It is recommended to store in a ventilated, low-temperature, dry warehouse, separate from oxidants and food additives.
Other customization details are not specified in the supplied information.
