Production method of high-temperature-resistant shading quartz glass plate

The invention discloses a production method of a high-temperature-resistant shading quartz glass plate, and belongs to the technical field of glass plates. The production method of the quartz glass comprises the following steps: preparing opaque quartz glass; preparing gel from tetraethoxysilane, absolute ethyl alcohol, distilled water, hydrochloric acid, ammonia water and formamide; and sintering the opaque quartz glass and the gel together to prepare the quartz glass. By adding hydrochloric acid, ammonia water and formamide, the particle surface of sol can adsorb a certain amount of H < + > in hydrochloric acid and generate Si-OH with three coordinates, OH-in ammonia water can generate SiO with three coordinates through vibration and chemical bond breakage, and SiO attacks Si atoms in the centers of other sol molecules, so that condensation polymerization is performed; after the formamide is added, the precursor generated by the system is a low polymer with less than 6 silicon atoms, and the condens
