| Chinese Name | 偏磷酸镁 |
| English Name | Magnesium Metaphosphate |
| CAS No. | 13573-12-1 |
| M.F | Mg(PO3)2 |
| M.W | 182.3 |
| Specification | MgO：22%±0.5%，P2O5：78%±1%，Fe2O3＜2ppm， Cu＜0.1ppm，Ni，Co，Mn，Pb，Cr＜1ppm |
| Applciation | Mainly used in special optical glass, special protective glass, refractory optical glass materials, phosphate glass. Fluorophosphate glass and laser nuclear fusion glass. Hardening rate slows down during glass forming. Reduce the crystallization tendency of glass, improve the chemical stability and mechanical strength. Especially low iron magnesium metaphosphate is one of the important raw materials of special protective glasses for modern national defense scientific research. It mainly replace the lead series protective glasses. |
