Description

technical field [0001] The invention belongs to the technical field of glass processing, and in particular relates to high-strength and high-temperature-resistant high borosilicate glass. Background technique [0002] High borosilicate glass (also known as hard glass), because the linear thermal expansion coefficient is (3.3 ± 0.1) × 10-6 / K, it is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source , craft jewelry and other industries. Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy, and developed countries such as Germany and the United States have carried out extensive promotion. [0003] However, the streng...
