Embodiment 1
[0040] When m=3, A is Bi, B is Si and Ti, and the specific expression is (Bi 2 o 2 ) 2+ (Bi 2 Ti 3-x Si x o 10 ) 2- , and then take x from 0.6, 1.2, 1.8 and 2.4 respectively, according to the molar ratio between the above metal elements, weigh the specific molar ratio of Bi 2 o3 、TiO 2 and SiO 2 , after mixing evenly, melt at 1250°C for 1.5 hours, then pour the resulting product into a corundum crucible at room temperature, the obtained product is as follows figure 1 shown. The background with words in the photo is mainly to illustrate the light transmittance of the glass. From left to right, the larger the value of x, the better the light transmittance and the clearer the writing.
[0041] When x=0.6, the obtained glass is as figure 1 As shown in (a), the mole fraction of the silicon element in the metal element at this time is 8.57 mol%, and a yellow translucent glass cannot be obtained. When x=1.2, 1.8, 2.4, the obtained glass is as follows figure 1 As shown in...
Embodiment 2
[0046] When m=3, A is Al and Bi, B is Si and Ti, the specific expression is (Bi 2 o 2 ) 2+ (BiAlTiSi 2 o 10 ) 2- , according to the molar ratio between the above metal elements, weigh a certain Bi 2 o 3 、Al 2 o 3 、TiO 2 and SiO 2 , after mixing evenly, melt at 1250°C for 1.5 hours, then pour the resulting product into a corundum crucible at room temperature, the obtained product is as follows Figure 8 shown.
[0047] The resulting product is a black opaque glass-like substance, and the energy spectrum test result of the resulting product is as follows: Figure 9 As shown, it can be seen from the figure that the product is a continuous glassy substance without obvious grain boundaries. The product contains only Bi 2 o 3 、Al 2 o 3 、TiO 2 and SiO 2 and other trace elements that can be ignored, and does not contain the B commonly found in traditional glasses 2 o 3 , alkali metals and alkaline earth metals, further proves that the formula provided by the presen...
Embodiment 3
[0049] For verifying the component expression of the present invention (Bi 2 o 2 ) 2+ (A m-1 B m o 3m+1 ) 2- The effectiveness of the traditional soda-lime silica glass is deliberately introduced Ca 2+ , according to the expression (Bi 2 o 2 ) 2+ (CaAlTiSi 2 o 8.5 ) 2- Weigh a certain amount of CaO, Bi 2 o 3 、Al 2 o 3 、TiO 2 and SiO 2 , after mixing evenly, melt at 1250°C for 1.5 hours, then pour the resulting product into a corundum crucible at room temperature, the obtained product is as follows Figure 10 shown.
[0050] Depend on Figure 10 It can be seen that the obtained product is yellow on the outside, flesh-colored near the center, without glass luster, with obvious granular boundaries, and is a ceramic-like substance, which further proves that the formula provided by the present invention does not contain common alkaline earth metals in traditional glass. New glass system.
