The Difference Between Soda Lime Glass And High Borosilicate Glass
May 31, 2023
Soda-lime glass and high borosilicate glass are two different types of glass that have distinct differences in their composition and properties.
Soda-lime glass, also known as soda-lime-silica glass, is the most common type of glass used in everyday products such as windows, bottles, and tableware. It is made by melting a combination of soda ash, limestone, and sand at a high temperature. This type of glass lacks the durability and strength of other types of glass, but it is inexpensive and easy to produce.
High borosilicate glass, on the other hand, is a specialized type of glass that is known for its exceptional heat resistance and chemical stability. It is made by melting a combination of boron oxide, silica, and other minerals at a much higher temperature than soda-lime glass. The addition of boron oxide to the glass mixture gives it a higher thermal expansion coefficient, making it more resistant to thermal shock and damage caused by sudden changes in temperature.
Other differences between soda-lime glass and high borosilicate glass include their refractive index and density. High borosilicate glass has a higher refractive index than soda-lime glass, which means that it bends light differently and appears clearer and brighter. It also has a lower density than soda-lime glass, which makes it lighter and more resistant to breakage.
Overall, the main difference between soda-lime glass and high borosilicate glass is their composition and properties, with high borosilicate glass being a more specialized and durable type of glass that is commonly used in laboratory equipment, cooking utensils, and other high-performance applications.
