New fluoride glass compositions have been investigated. These were prepared by introducing cations into the basic ZnF2-InF3-GaF3-PbF2-LaF3 glass system. Incorporation of cadmium strongly increased thermal stability. Addition of zirconium or hafnium improves the critical cooling rate of these compositions.
