Product name : Zinc Metaphosphate
Molecular formula: Zn (PO3) 2
Molecular weight: 223.33
APPLICATION:
Mainly used in special optical glass, special protective glass and radiation-resistant optical glass materials, additives in phosphate glass, fluorophosphate glass and laser nuclear fusion glass. The additives in the glass can slow down the hardening speed when the glass is formed. Reduce the crystallization tendency of glass and improve the chemical stability and mechanical strength of glass. Magnesium metaphosphate, especially low-iron magnesium metaphosphate, is one of the important raw materials for the series of glasses for special protective purposes in modern national defense scientific research. Foreign countries have mainly replaced the lead series of protective glass and introduced 5-20% of
magnesium metaphosphate into the glass system. Data provided refer to.
