Germanate and fluoroaluminate glasses have potential applications as windows and dome in the field of middle-infrared （MID-IR）. In order to remove the residual water in germanate glass, some fluoride were added into the composition. Experimental results indicated that the content of OH group decreased with fluoride increasing. When the melting temperature was increased, the transmitting spectrum was obtained without absorption of hydroxyl. For fluoroaluminate glasses easily forming crystal dur- ing cooling, tellurium dioxide was doped into the fluoride glasses, the glass forming ability was improved and the glass could be easy to fabricate bulk. Meanwhile some physical and chemical properties of the two types of infrared material were reported.
