Aluminum Metaphosphate

Product specifications: Al2O3:19%±0.5%, P2O5:81%±1%, Fe2O3 < 2PPM, Cu < 0.1ppm, Ni, Co, Mn, Pb, Cr < 1PPM
Use: as phosphate glass. Fluorophosphate glass and laser fusion glass additive. In oxygen phosphate glass, it has better moisture resistance and lower refractive index than other phosphate metaphosphates, and the Abbe number is also larger, so the UV part of the glass is relatively low, which can improve the thermal stability, chemical stability and high mechanical strength of the glass. It can also be used as a high temperature binder to improve the compressive performance of the prefabricated parts. High purity aluminum metamophosphate is a special factor material in semiconductor silicon.
Properties: glassy powder, insoluble in water
Package: 500g/bag, 20kg/barrel
