what is silica glass


Silica glass, also known as fused quartz, is a type of glass composed of silicon dioxide (SiO2). Its composition is one of most stable forms of glass, known for its extreme heat and chemical resistance. Silica glass is more expensive than other types of glass due to its qualities, but is used in applications where temperature, acid resistance, and purity are essential.

Silica glass has been around for thousands of years, and was also used by ancient Egyptians to make crystal vessels, decorations, and jewelry due to its attractive luster. More recently, its use in glass industry has increased due to its special properties.

The most significant properties of silica glass are its high degree of thermal and chemical stability, strength and ability to resist high temperatures. It is a relatively low-cost and versatile material, and can be used in applications such as lenses, automotive components, lighting, and even medical implants.

Silica glass is made primarily out of quartz, a mineral found in large deposits in Earth. Quartz is ground down and mixed with other materials such as sodium oxide, potash, and borax. This mixture is heated to very high temperatures and fused together to create glass. The result is a transparent, non-porous, durable material that is resistant to acids and alkalis.

Since silica glass can withstand temperatures up to 1200°C, it is often used for laboratory equipment, semiconductor manufacturing, and production of specialty glass products. In addition, its chemical resistance makes it ideal for pharmaceutical products, medical instruments, and laboratory equipment, as well as for dishes and cookware.

When using silica glass, it is important to be aware that it is brittle and may easily break if exposed to abrupt temperature changes. It is also important to handle it carefully and with safety in mind, as it contains chemicals that can be harmful if inhaled.
