Nitrogen/Oxygen Substitution within PO4 Tetrahedra: A Right Answer to the Poor Chemical Durability of Phosphate Glasses
Published online by Cambridge University Press: 16 February 2011
Abstract
By using both alumina addition and nitrogen/oxygen substitution within PO4 tetrahedra, it is possible to prepare durable phosphate glasses without affecting their specific properties such as low melting temperatures and high thermal expansion coefficients. In particular, “LiKMgAlPON” nitrogen-rich glass compositions have a chemical durability on the same order as soda lime window glass, associated with a glass processing temperature as low as 800°C.
