锗酸盐和氟铝酸盐透红外玻璃材料作为窗口或头罩材料具有广泛的应用前景。结合锗酸盐玻璃含有少量水的问题,在成分中引入氟化物,实验表明:随氟化物含量增加,玻璃中羟基含量逐渐降低。同时通过对熔制温度的调整,获得了不含羟基的红外玻璃。针对氟铝酸盐玻璃在冷却过程中易析晶的问题,在氟化物组分中加入少量重金属氧化物TeO2,得到析晶性能好的氧氟铝酸盐玻璃。同时给出了两类红外材料的一些物理、化学性质。
Germanate and fluoroaluminate infrared glass materials have wide application prospects as a window or hood material. In combination with the fact that germanate glass contains a small amount of water, fluoride is introduced into the composition. Experiments show that as the fluoride content increases, the hydroxyl content in the glass gradually decreases. At the same time by adjusting the melting temperature, obtained without hydroxyl infrared glass. Aiming at the problem of easy crystallization of fluoroaluminate glass during the cooling process, a small amount of heavy metal oxide TeO2 is added to the fluoride component to obtain the oxyfluoride aluminate glass with good crystallization performance. At the same time, some physical and chemical properties of two kinds of infrared materials are given.
