Ring Shaped Quartz SiO2 Sputtering Target For Vacuum Coating

The quartz ring is a ring-shaped sputtering target made primarily of high-purity silicon dioxide (SiO2), widely used in vacuum coating processes for optoelectronics, semiconductors, and optical films. Quartz rings feature high light transmittance, low thermal expansion coefficient, and excellent chemical stability, with a refractive index of 1.46 (at 500nm) and transparency from 200-9000nm. They maintain structural stability under high temperature and vacuum conditions, making them important materials for optical coatings, conductive films, and protective films.

Outstanding Characteristics of Quartz Ring

l High Purity Material

Utilizing high-purity quartz is critical for defect reduction, ensuring superior thin-film quality and integrity.

l Excellent Optical Properties

It has high transmittance in the ultraviolet, visible, and infrared wavelengths, making it suitable for optical coating applications.

l Strong Thermal Stability

It is resistant to high temperatures and not easily cracked due to thermal stress with a low thermal expansion coefficient which makes it an ideal choice for high-energy sputtering environments.

l Chemical Inertness

It has excellent corrosion resistance to acids, alkalis, and most chemicals, ensuring purity during coating process.

Wide Applications of Quartz Ring

l Optical Device Manufacturing

Used in the deposition of protective or anti-reflective layers for optical lenses, filters, and coated glass.

l Semiconductor Manufacturing

Used in semiconductor processes for the preparation of insulating layers, meeting high purity requirements.

l Photovoltaic Industry

Used as a functional layer material in photovoltaic cell modules to enhance the light transmittance and weather resistance.

l Display Devices

Used in the deposition of protective films and insulating films for flat-panel displays and touch panels.

l Decorative Coatings

Used to prepare wear-resistant, corrosion-resistant, and high-transmittance decorative films, improving aesthetics and extending service life.
