Vidros fosfatos são investigados desde a década de 50, sendo obtidos a partir da fusão de compostos inorgânicos em temperaturas relativamente baixas (1000- 1200oC), apresentando baixas temperaturas de transição vítrea. No entanto, estes vidros são sensíveis a ambientes com altas umidades relativas, mostrando certa fragilidade em relação à durabilidade química. Vidros fosfatos de ferro foram obtidos previamente a partir da fusão de precursores inorgânicos apropriados, tanto em fornos de indução, como em fornos elétricos convencionais. A presença de ferro promove o aumento da durabilidade química, suficiente para possibilitar o uso destes materiais como meio imobilizador de rejeitos radioativos ou como fibras de resistência mecânica, adequada...
