摘要：

Fluoroindate glasses are more transparent in the IR spectrum than standard fluorozirconate glasses. The shift of the multiphonon absorption edge makes it necessary to reduce the resident content of sulphate impurities which induce a strong optical absorption between 8 and 9-mu-m. The chemical elimination of sulphate has been implemented by a zirconium-assisted reduction or by the incorporation of fluoropolymers before melting.
