Quartz Disc

Specification and Details of Quartz Disc

Quartz disc is made from fused silica, a high-purity form of silicon dioxide (SiO₂) known for its exceptional chemical and thermal properties. It is used in high-temperature processes, including steel production, glass manufacturing, and investment casting. Fused silica exhibits excellent resistance to thermal shock and remains chemically stable against most acids, except hydrofluoric acid. Under moderate conditions, it is unaffected by water or steam.

Quartz disc uses advanced techniques that involve careful grinding and polishing to ensure it is evenly thick and has smooth surfaces. This precision makes the disc perfect for uses requiring exact specifications, like in optical systems and research involving thin films. The high purity of fused quartz, which can be as much as 99.99%, makes it perform exceptionally well, especially in harsh environments where stability under heat and chemicals is crucial.

High-quality quartz sand and crystal flour are heated in furnaces to make ultra-pure quartz. These are then shaped into different forms, such as discs, sheets, cylinders, and rods, to fit various industrial purposes. Laser cutting is used to get the exact sizes needed, and the edges are smoothed to ensure they are safe to handle. Quartz products come in different styles, including transparent, opaque, and arc-fused, each tailored for specific applications.

Quartz disc offer outstanding thermal resistance and chemical inertness, enabling its use in environments where standard materials fail. Its adaptability and high performance make it indispensable in industries requiring reliable and durable materials for advanced applications.

Applications of Quartz Disc

Due to its unique properties, quartz glass disc is used in many fields. It is used in applications that require durable materials in the aviation industry. In semiconductor manufacturing, quartz is essential for producing electronic components. It is also vital in developing laser technology, where precision is crucial. The disc is used in infrared heat sensors to measure temperature effectively and is found in optical windows allowing light to pass through while blocking other elements. Quartz glass discs help with heat diffusion and filter corrosive liquids and gases by regulating the flow of these substances. Quartz disc is used in various experiments in research and development laboratories. It also has applications in medical technology, solar energy systems, and telecommunications, where its reliability and performance are essential.

How to use Quartz Disc?

• Clean the quartz disc with a soft, lint-free cloth to remove dust or debris.
• Rinse the disc with distilled water to ensure it's free from contaminants.
• Place it securely on the desired apparatus (e.g., a microscope or spectrometer).
• Ensure that it fits properly, without any gaps that could cause instability.
• Avoid over-tightening when securing the disc to prevent stress fractures.
• If the disc is used in high-temperature environments, preheat it gradually to prevent thermal shock.
• Use appropriate wavelengths for optical purposes (like spectroscopy).
• After use, clean the disc again to remove any residues or contaminants.
• Place the disc in a protective cover to avoid scratches or damage.
• Always handle the discs with clean hands to prevent contamination and protect the disc from oils or particles on your hands.
• Place the disc in a padded case or use bubble wrap to protect it from impacts when transporting.
• Do not stack the discs directly on top of one another. Use separators to prevent scratches.
• Do not expose the disc to chemicals or solvents unless specifically tested for compatibility.
• Avoid exposing the quartz disc to high humidity, direct sunlight, or corrosive environments.

Safety Guidelines

• If using quartz discs in laser or UV light applications, wear appropriate eye protection to prevent harm from exposure.
• Use cut-resistant gloves when handling or machining quartz to avoid injury.
• Avoid rapid temperature changes to prevent thermal shock, which can cause the disc to crack or shatter.
• Handle broken quartz carefully, as the edges can be sharp and pose a cutting hazard.
• Dispose of broken pieces in a designated glass disposal container, as per local hazardous waste guidelines.
• Quartz is chemically stable, but avoid prolonged exposure to strong alkalis or hydrofluoric acid, as it can etch or damage the surface.
• If the quartz disc breaks during use, power down the equipment immediately to prevent further damage or hazards.
• Inspect the surrounding area for shards or fragments to ensure safety and clean up using proper tools.
