Embodiment 1
[0033] According to the above recipe 1 # Calculate the weight percent of the glass from the molar composition in the glass, and then weigh 10Kg of raw materials and mix them evenly. Add the prepared powder into the crucible one by one, heat and melt through the electric melting furnace, the melting temperature is controlled at about 1200°C, the melting time is 24 hours, and the glass liquid is stirred during the melting process. After the molten glass is clarified, inject the molten glass into the preheated mold, and quickly put the glass into the muffle furnace that has been heated up. First, keep it warm at the transition temperature Tg of the glass for 2 hours, and then heat it at 10°C / hour. Anneal at a speed of 50°C, close the muffle furnace, cool down to room temperature, and finally take out the finished product.
[0034] Take 10 mg of the annealed sample, grind it into a very fine powder with an agate bowl, and conduct differential thermal analysis. T of the tested sa...
