In our daily life, glass products can be found everywhere, but many people may not be aware of the significant differences between quartz glass plate and ordinary glass.

Material Composition

Ordinary glass is mainly composed of sodium silicate, calcium silicate and silicon dioxide. These components make ordinary glass have a certain degree of transparency and hardness, but there are some limitations.

Quartz glass plate, on the other hand, is based on high-purity silicon dioxide as the main raw material. Typically, its silica content can reach 99.9% or more. This high purity material gives quartz glass many unique properties.

Physical Properties

1. Hardness

Ordinary glass has relatively low hardness and is easily scratched. Quartz glass has a very high hardness, second only to diamond, silicon carbide and other super-hard materials. This makes the quartz glass plate able to resist all kinds of abrasion and scratches in the process of use, and keep the transparency and finish for a long time.

2. High temperature resistance

Ordinary glass is easy to soften and deform or even break under high temperature. Generally speaking, the softening point of ordinary glass is about 600℃. However, quartz glass has excellent high-temperature resistance and can be used for a long time at temperatures up to 1200℃ without deformation or rupture. This makes quartz glass plate widely used in high-temperature environments, such as high-temperature furnaces in laboratories and semiconductor manufacturing equipment.

3. Thermal Stability

Ordinary glass has a large coefficient of thermal expansion, which is prone to thermal stress and rupture when the temperature changes. The thermal expansion coefficient of quartz glass is very small, only about 1/10 of that of ordinary glass. This makes the quartz glass plate able to maintain better stability during temperature changes and is not easy to break.

4. Optical Properties

The optical performance of ordinary glass is relatively poor, with a low transmittance of ultraviolet and infrared rays. On the other hand, quartz glass plate has good optical properties, with high transmittance to ultraviolet, visible and infrared rays. This makes quartz glass plate has a wide range of applications in the field of optics, such as the manufacture of optical instruments, optical fiber and so on.

Chemical Properties

1. Corrosion resistance

Ordinary glass is susceptible to corrosion by acids, alkalis and other chemicals, especially in the case of long-term contact. But quartz glass plate has strong corrosion resistance and can resist the erosion of various acids, alkalis, salts and other chemicals. This makes quartz glass plate have important applications in chemical experiments, chemical production and other fields.

2. Purity

Ordinary glass may contain some impurities, such as iron, copper and other metal ions, which will affect the performance and appearance of the glass. The purity of quartz glass plate is very high, almost does not contain any impurities, which makes it has an irreplaceable role in some of the fields that require high purity, such as semiconductor manufacturing, biomedicine and so on.

Application areas

1. Ordinary glass

Due to the low cost of ordinary glass and relatively simple production process, it is widely used in construction, home, automobile and other fields. For example, window glass, glassware, car windshield, etc. are made of ordinary glass.

2. quartz glass plate

Quartz glass plate is mainly used in high-tech fields due to its unique properties. Such as in the semiconductor manufacturing, quartz glass is used as a wafer carrier and reaction chamber lining; in the optical field, quartz glass is used to manufacture high-precision optical instruments and optical fibers; in the laboratory, quartz glass is used to manufacture high-temperature, corrosion-resistant experimental apparatus.

There are significant differences between quartz glass plate and ordinary glass in terms of material composition, physical properties, chemical properties and application areas. Understanding these differences helps us to choose the right glass material for different occasions to meet various application requirements.
