Embodiment 1-7

[0077] Weigh the components as shown in Table 1, mix them evenly, pour them into a platinum crucible, keep them warm at 1640°C for 3.5 hours, use a platinum rod to stir and discharge air bubbles to homogenize the glass liquid, and then pour the melted glass liquid Put it into a stainless steel cast iron mold to shape it into a specified block glass product, then anneal the glass product in an annealing furnace for 2 hours, turn off the power and naturally cool to room temperature. The glass products are cut, ground, polished, cleaned with deionized water and dried. Next, the obtained glass product is thinned by a secondary drawing method, and the thickness of the thinned glass is 85 μm.

[0078] The properties of the prepared glass products were tested respectively, and the results are shown in Table 1.

Abstract

The invention relates to the field of glass manufacturing, and discloses a glass composition, alkaline lithium aluminum silicate glass and application of the alkaline lithium aluminum silicate glass. The composition for the glass comprises the following components in percentage by weight on the basis of the total weight of the composition for the glass: 45 to 75 weight percent of SiO2, 5 to 27 weight percent of Al2O3, 4 to 15 weight percent of Li2O, 4 to 8.5 weight percent of Na2O, 0.05 to 2.5 weight percent of SnO2, 0.002 to 0.7 weight percent of ZrO2, 0.001 to 0.02 weight percent of Fe2O3, 0.001 to 4.5 weight percent of ZnO, 0.3 to 8 weight percent of CeO2, 0.005 to 2.5 weight percent of MgO and 0.005 to 1 weight percent of Sb2O3, and the composition for the glass does not contain P2O5 and / or B2O3. When the composition for glass provided by the invention is used for preparing the glass, the glass has excellent ultraviolet light absorption resistance and mechanical properties.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to glass composition, alkaline lithium aluminosilicate glass and applications thereof. Background technique [0002] There are radiations from cosmic rays and solar particles in outer space. When a spacecraft is operating in outer space, it will be damaged by space high-energy particles and rays, which will cause the solar panel of the spacecraft to be broken down and lose its function. In order to protect the solar cells, a glass cover is usually added to the solar cells. However, when ordinary colorless glass is used in an outer space environment, it will cause changes in color and transmittance under the radiation of various high-energy particles or rays, which will lead to deterioration of the glass and cannot guarantee sufficient sunlight transmittance. Deprive the spacecraft of a reliable electrical supply. Therefore, a special space is required to protect the solar cell w...
