Borosilikaatista

Borosilikaatista is a type of glass known for its exceptional thermal shock resistance and chemical durability. Its composition typically includes silicon dioxide and boron oxide, along with smaller amounts of other oxides like sodium oxide and aluminum oxide. This specific blend of ingredients gives borosilicate glass its unique properties, distinguishing it from common soda-lime glass.

The primary advantage of borosilicate glass is its ability to withstand rapid and significant temperature changes without cracking or breaking. This is due to its low coefficient of thermal expansion. When heated, the glass expands minimally, and when cooled, it contracts minimally. This makes it ideal for applications where temperature fluctuations are common.

Furthermore, borosilicate glass exhibits excellent resistance to chemical corrosion from most acids, alkalis, and organic solvents. This inertness makes it suitable for use in laboratories, chemical processing, and food storage where contamination or reaction with the container material must be avoided.

Common uses for borosilicate glass include laboratory glassware such as beakers, flasks, and test tubes. It is also widely used in the manufacturing of cookware, bakeware, and high-quality drinking glasses due to its durability and resistance to staining and odors. In the lighting industry, it is used for certain types of bulbs and lenses. Its thermal and chemical properties also find applications in specialty areas like sight glasses in industrial equipment and components in optical instruments.
