Product name : Potassium Metaphosphate
Molecular formula: (KPO3) 6
Molecular weight: 708.4
PRODUCT PROPERTIES:
Potassium metaphosphate glass material, glass powder, specific gravity: 2.30, melting point: 807°C, PH value (1%) =3, boiling point :1320°C, refractive index: 1.458-1.575.APPLICATION:Mainly used in special optical glass materials, phosphate glass, fluorophosphate glass, laser nuclear fusion glass
additives. Potassium metaphosphate its role is similar to sodium metaphosphate, the radius of potassium ions is larger than sodium ions, the viscosity of potassium glass is larger than sodium glass, can reduce the crystallization tendency of glass, increase the transparency and luster of glass, the introduction of potassium can effectively reduce the surface tension of glass, glass hardening speed is slow, and it is also a clarifying agent, discoloration agent and oxidant of glass. 5-15% of the glass is introduced. Data for reference.
