In the glass family, high borosilicate glass stands out with excellent heat resistance and is known as the "king of glass". It can maintain stability under extreme temperature changes, making it the preferred material for laboratories and high-end kitchenware.
The heat resistance of high borosilicate glass comes from its unique chemical composition. It contains 12% -15% boron trioxide, which significantly reduces the coefficient of thermal expansion, making it less prone to expansion at high temperatures and less prone to contraction at low temperatures. This characteristic enables it to withstand high temperatures up to 500 ℃ and low temperatures as low as -60 ℃, even if the instantaneous temperature difference reaches 200 ℃, it will not rupture.
This excellent heat resistance makes it widely used in multiple fields. In the laboratory, it is used to manufacture beakers, test tubes, and other vessels that can be directly heated without breaking; In high-end kitchenware, it is used to make heat-resistant glass cookware that can be directly placed from the refrigerator into the oven; In the field of optics, it is used to manufacture telescope lenses and adapt to extreme temperature difference environments.
The heat resistance of high borosilicate glass is not only reflected in its physical properties, but also promotes technological progress in related industries. It provides reliable tools for scientific experiments, improves cooking efficiency, and promotes the development of optical technology. With the advancement of technology, the application prospects of high borosilicate glass will become even broader, continuing to consolidate its position as the "king of glass".
