Embodiment 1
[0014] A glass comprising 1 part of silicon dioxide, 1 part of aluminum oxide, 0.2 part of sodium hydroxide, 1 part of bismuth oxide, 3 parts of ethyl orthosilicate and 3 parts of hydroxybenzone.
[0015] A method for making glass, comprising the steps of:
[0016] In the first step, 1 part of silicon dioxide, 1 part of aluminum oxide, 0.2 part of sodium hydroxide, 1 part of bismuth oxide and 3 parts of oxybenzone are mixed.
[0017] In the second step, put the mixture in the previous step into a melting furnace at a pressure of 100-Mpa and a temperature of 500 degrees centigrade for 1 hour for smelting, and then add 3 parts of tetraethyl orthosilicate and 3 parts of hydroxybenzophenone.
[0018] The third step is to pour the glass water obtained in the upper part into the mold, anneal naturally to normal temperature, open the mold and demould, and obtain glass.
Embodiment 2
[0020] A glass comprising 10 parts of silicon dioxide, 2 parts of aluminum oxide, 0.8 parts of sodium hydroxide, 2 parts of bismuth oxide, 5 parts of ethyl orthosilicate and 7 parts of hydroxybenzophenone.
[0021] A method for making glass, comprising the steps of:
[0022] In the first step, 10 parts of silicon dioxide, 2 parts of aluminum oxide, 0.8 parts of sodium hydroxide, 2 parts of bismuth oxide and 7 parts of oxybenzone are mixed.
[0023] In the second step, put the mixture in the previous step into a melting furnace at a pressure of 200 MPa and a temperature of 1000 degrees Celsius for 2 hours for smelting, and then add 5 parts of tetraethyl orthosilicate and 7 parts of hydroxybenzophenone.
[0024] The third step is to pour the glass water obtained in the upper part into the mold, anneal naturally to normal temperature, open the mold and demould, and obtain glass.
Embodiment 3
[0026] A glass comprising 7 parts of silicon dioxide, 1.5 parts of aluminum oxide, 0.28 parts of sodium hydroxide, 1.5 parts of bismuth oxide, 3.7 parts of tetraethyl orthosilicate and 4 parts of hydroxybenzophenone.
