Embodiment 1
[0028] Composition as in Table 1 1 # As shown, the specific preparation process is as follows:
[0029] According to table 1 in 1 # The mole percentage of the glass composition, calculate the corresponding weight of each composition, weigh the raw materials and mix them uniformly; put the mixture into a corundum crucible and melt it in a silicon carbide rod electric furnace at 1200 ° C, and clarify it for 15 minutes after the mixture is completely melted. Minutes, pour the molten glass into the preheated mold; quickly move the glass into a muffle furnace that has been heated to 420°C, keep it warm for 10 hours, then lower it to room temperature at a rate of 10°C / hour, and take out the glass after cooling completely sample.
[0030] The test results for this glass are as follows:
[0031] Take a small sample after annealing, grind it into a fine powder with an agate mortar, and conduct a differential thermal analysis test. The differential thermal curve of the mid-infrared ...
