Aluminum metaphosphate has good moisture resistance in chlorophosphate glass
Aluminum metaphosphate is a chemical, glassy powder.Cations with high field strength and other cations can also be filled with the short chain. In production, the electrostatic attraction with fluoride or oxygen ions to unite the short chain is conducive to the inhibition of glass permeability. When the amount of aluminum metaphosphate is higher than 85%, the structure of glass is seriously damaged.
Mainly used in special optical glass, phosphate, Phosphate glass, fluorophosphate glass and laser fusion glass additives, aluminum metaphosphate in fluoride phosphate glass is better than other metaphosphate tide resistance and low refractive index, abbe number is larger, then make the ultraviolet part of the dispersion is lower, the glass chemical stability and high mechanical strength, chemical stability a 3 orders of magnitude higher than cobalt-based fluoride glass.
