Embodiment 1
[0020] A barium glass material prepared from the following raw materials according to the stated weight (Kg), SiO 2 :67;B 2 o 3 : 1.70; Al 2 o 3 : 1.00; CaO: 3; ZnO: 1.80; BaO: 8; K 2 O: 4; Na 2 O: 13.
[0021] The specific production method of barium glass material is: from heating the raw material to melting the molten glass, it can be divided into the following five stages according to the different melting processes: The first stage of silicate formation: during the heating process, the raw material SiO 2 :67;B 2 o 3 : 1.70; Al 2 o 3 : 1.00; CaO: 3; ZnO: 1.80; BaO: 8; K 2 O: 4; Na 2 After the composition of O:13 undergoes chemical and physical changes, most of the gas products have been developed. At this stage, the main reaction process of glass melting is completed, and the glass raw materials are converted into silicate and SiO 2 Composed of opaque sintered products; and for the produced soda-lime-silica glass, the temperature at this stage is completed at 8...
