Borosilikaatti

Borosilikaatti is a type of glass that is primarily composed of silica (SiO2) and boron oxide (B2O3). It is known for its excellent resistance to thermal shock, chemical corrosion, and high-temperature stability. This makes it suitable for applications where durability and reliability are critical, such as in laboratory glassware, high-temperature furnaces, and certain types of optical components.

The unique properties of borosilikaatti are attributed to its chemical composition and the way it is manufactured. The addition of boron oxide to silica glass lowers the melting point and increases the fluidity of the glass, allowing for easier processing and shaping. However, it also reduces the glass's resistance to thermal shock compared to pure silica glass.

Borosilikaatti is typically produced using a float glass process, where molten glass is floated on a bed of molten tin. This method allows for the production of large, flat sheets of glass with high precision and consistency. The glass is then cooled and annealed to relieve any internal stresses and improve its mechanical properties.

Borosilikaatti is available in various forms, including sheets, tubes, and rods, each with its own set of properties and applications. It is often used in scientific research, industrial processes, and high-tech industries due to its exceptional resistance to extreme conditions. However, its use is not without limitations. For instance, it is not suitable for applications requiring extreme chemical resistance, as it can be affected by certain acids and alkalis. Additionally, its thermal expansion coefficient is higher than that of pure silica glass, which can limit its use in applications where dimensional stability is critical.
