Product Description

Product Description

Aluminum Metaphosphate As a professional manufacturer of inorganic chemical materials, we supply high-quality Aluminum Metaphosphate (Chemical Formula: Al(PO3)3) with stable performance and reliable purity. This inorganic salt compound is widely recognized in industries such as optical glass, ceramics, and coatings due to its excellent chemical stability and unique physical properties.

Aluminum Metaphosphate is a white, odorless, and tasteless powder or granular solid. It is insoluble in water and most organic solvents, and exhibits outstanding heat resistance, acid resistance, and wear resistance. Our product strictly complies with international quality standards, with a purity of up to 99% or higher, ensuring consistent performance in various application scenarios.
Key Performance Advantages
1.Superior Purity: Advanced purification technology reduces impurity content (such as Fe, Ca, Mg) to less than 0.1%, avoiding adverse effects on the quality of end products.
2.Excellent Thermal Stability: Maintains stable chemical structure at high temperatures (melting point: ~1590°C), suitable for high-temperature processing procedures.
3.Strong Chemical Inertness: Resists corrosion from most acids and alkalis, ensuring long-term service life of products.
4.Uniform Particle Size: Customizable particle size distribution (100-1000 mesh) for easy dispersion and mixing with other materials.Specification

Usage Instructions for Aluminum Metaphosphate1. As a Flame Retardant Additive (in Polymers/Resins)- Preparation: Ensure the aluminum metaphosphate powder (particle size 10-50μm) is dry (moisture ≤0.5%) to avoid agglomeration.- Mixing: Add 15-30 wt% of aluminum metaphosphate to the base polymer (e.g., polyester, epoxy resin) during the melting/extrusion process. Stir at 100-150°C for 10-15 minutes to achieve uniform dispersion.- Processing: Proceed with molding (injection, extrusion) at the polymer's standard processing temperature (avoid exceeding 200°C for long periods to preserve flame-retardant performance).- Curing (if applicable): For thermoset resins, cure at 120-180°C as per the resin's specifications; the aluminum metaphosphate will form a protective char layer during combustion.2. As a Ceramic Sintering Aid- Formulation: Blend 3-8 wt% of aluminum metaphosphate with ceramic raw materials (e.g., alumina, zirconia) and a small amount of binder (e.g., PVA solution).- Shaping: Mold the mixture into the desired ceramic green body (pressing pressure: 10-20 MPa).- Sintering: Heat the green body in a kiln:Ramp up to 800°C at 5°C/min (to remove the binder).Raise to 1400-1600°C at 3°C/min; hold for 2-4 hours (aluminum metaphosphate lowers the sintering temperature and improves densification).Cool to room temperature at 4°C/min to avoid cracking.3. As a Corrosion Inhibitor (in Coatings)- Dispersion: Disperse 5-10 wt% of aluminum metaphosphate into the coating base (e.g., acrylic, epoxy coating) using a high-speed stirrer (1500-2000 rpm) for 20 minutes.- Application: Apply the coating to the metal surface (pre-cleaned and degreased) via spraying or brushing; control the wet film thickness to 50-100μm.- Drying/Curing: Air-dry at room temperature for 2 hours, then cure at 80-120°C for 1 hour. The aluminum metaphosphate will form a passive film to resist corrosion.Safety Notes- Avoid inhalation of dust; wear a dust mask during handling.- Store in a dry, cool area away from strong acids (which may react with the product).- Dispose of unused material as industrial non-hazardous waste.Application

1. Optical Glass Manufacturing
As a critical additive in optical glass production, it plays three core roles. First, it enhances the glass's transparency by reducing internal impurities and bubble formation. Second, it adjusts the glass's refractive index, helping manufacturers produce lenses, prisms and optical fibers that meet precise optical performance requirements. Third, it improves the glass's mechanical strength and scratch resistance, extending the service life of optical components used in cameras, telescopes and communication equipment.
2. Ceramic & Enamel Industry
In ceramics, it acts as an efficient flux. It lowers the sintering temperature of ceramic raw materials by 50-100°C, reducing energy consumption while promoting denser ceramic structures—this enhances the ceramics' water resistance and impact resistance, suitable for producing high-quality sanitary ware and industrial ceramics. In the enamel sector, it functions as an opacifier and adhesion promoter. It makes enamel surfaces more uniform and glossy, and strengthens the bonding between enamel and metal substrates, preventing peeling and corrosion in kitchenware and industrial enameled tanks.
3. Flame Retardant Sector
It is a green, halogen-free flame retardant raw material widely used in plastics, rubber and building materials. When exposed to high temperatures, it decomposes to form a dense inorganic coating on the material surface. This coating blocks the exchange of heat and oxygen, effectively inhibiting combustion. Unlike traditional halogenated flame retardants, it does not release toxic gases during combustion, complying with global environmental standards (such as EU RoHS) and is ideal for flame-retardant modification of wire and cable insulation materials, furniture plastics and interior wall coatings.
4. Other Emerging Applications
In the electronics industry, it is used as a filler in high-temperature-resistant electronic adhesives, ensuring the adhesives maintain stability in harsh environments like circuit boards. In the refractory material field, it is added to refractory bricks and castables, improving their resistance to thermal shock and chemical erosion for use in industrial kilns and steelmaking furnaces.Company Profile
