Boroszilikátüveg

Boroszilikátüveg is a type of glass known for its exceptional resistance to thermal shock. This unique property makes it highly desirable for applications where rapid temperature changes are common. Its composition primarily includes silica and boron trioxide. The presence of boron trioxide significantly lowers the coefficient of thermal expansion compared to standard soda-lime glass. This low expansion means that when the glass is heated or cooled, it deforms very little, preventing the buildup of internal stress that can lead to breakage.

The manufacturing process for borosilicate glass involves carefully melting the raw materials at high temperatures and then shaping the molten glass. Its chemical inertness is another key characteristic, meaning it does not react with most chemicals, making it ideal for laboratory equipment, food containers, and pharmaceutical packaging. Borosilicate glass is also known for its clarity and durability. Common uses include laboratory glassware such as beakers and test tubes, bakeware, cookware, light bulbs, and even in telescope mirrors due to its stability. Its widespread adoption stems from its balance of thermal, chemical, and mechanical properties.
