As a high-performance material, quartz glass has been widely used in many industrial fields. Among them, its acid corrosion resistance is one of the important reasons for its wide application.

The basic characteristics of quartz glass

Quartz glass is mainly composed of silicon dioxide (SiO₂) and is a high-purity glass material. It has many unique physical and chemical properties, such as high transparency, high heat resistance, high insulation, and high chemical stability, etc. These characteristics make quartz glass irreplaceable in many fields.

The acid corrosion resistance of quartz glass

Quartz glass performs excellently in terms of chemical stability, especially its resistance to acid corrosion. Except for hydrofluoric acid (HF) and hot phosphoric acid, quartz glass hardly reacts chemically with other acids. This is because the silica structure in quartz glass is stable and difficult to be destroyed by other acids.

Specifically, the acid resistance of quartz glass is 30 times that of ceramics and 150 times that of stainless steel. At high temperatures, the chemical stability of quartz glass is more outstanding, which is unparalleled by any other engineering materials. This excellent acid corrosion resistance makes quartz glass widely used in fields such as semiconductors, chemical industry, and electronics that require high corrosion resistance.

The application of quartz glass resistant to acid corrosion

Semiconductor industry: The semiconductor industry has strict requirements for the alkali metal and heavy metal content in vehicles, and general materials cannot have such high acid resistance. Quartz glass, with its excellent acid corrosion resistance, has become an indispensable supporting material in the semiconductor industry. It can be made into diffusion tubes, cleaning tanks, etc., which are used in key processes such as diffusion and etching in semiconductor manufacturing.

Chemical industry: In the chemical industry, many chemical reactions need to be carried out in high-temperature, high-pressure, and highly corrosive environments. Quartz glass, due to its high heat resistance and corrosion resistance, becomes one of the commonly used materials in chemical equipment. It can be made into reaction kettles, pipelines, valves, etc., to ensure the smooth progress of chemical reactions.

Electronics industry: In the electronics industry, quartz glass is widely used in the manufacture of electric light sources, semiconductor communication devices, lasers, optical instruments, etc. These devices require high corrosion resistance and transparency of materials, and quartz glass just meets these requirements.

Other fields: In addition to the above-mentioned fields, quartz glass is also widely used in laboratory instruments, electrical equipment, medical equipment, and high-temperature and corrosion-resistant chemical instruments, etc. In these fields, the acid corrosion resistance of quartz glass provides a strong guarantee for the normal operation of equipment.

Notes on the acid corrosion resistance of quartz glass

Although quartz glass has excellent acid corrosion resistance, the following points still need to be paid attention to during its use:

Avoid contact with hydrofluoric acid: Hydrofluoric acid is one of the few acids that can chemically react with quartz glass. Therefore, when using quartz glass, it should be avoided to contact with hydrofluoric acid to prevent corrosion.

Pay attention to temperature control: Although quartz glass has excellent chemical stability at high temperatures, too high a temperature may still cause its performance to decline. Therefore, when using quartz glass, we should pay attention to controlling the temperature and avoid it exceeding its tolerance range.

Keep clean: The surface of quartz glass should be kept clean to avoid contamination. Pollutants may affect its corrosion resistance and reduce its lifespan.

Quartz glass, as a high-performance material, performs excellently in terms of acid corrosion resistance. Its unique chemical stability and physical properties make it widely used in semiconductors, chemical industry, electronics, and other fields.
