Single Crystal Quartz Wafers

Quartz crystal wafers are precision-cut slices of crystal quartz (SiO2), renowned for their exceptional properties and critical applications in the electronics industry. These wafers are produced from monocrystalline quartz, which is characterized by its anisotropic monoaxial crystal structure and trigonal configuration, consisting of silica-oxygen tetrahedrons arranged spirally.

The unique properties of quartz crystal wafers, such as piezoelectricity, high mechanical and chemical stability, and a very high Q factor at resonance, make them indispensable in frequency control and timing applications. They are commonly used in the manufacturing of oscillators, resonators, and filters, ensuring accurate frequency control in various electronic devices.

Quartz crystal wafers can be cut in different orientations, including X-Cut, Y-Cut, AT-Cut, and ST-Cut, to meet specific application requirements. Each cut offers distinct advantages in terms of frequency stability and temperature performance. Modern production techniques allow for the creation of extremely pure synthetic quartz, further enhancing the performance and reliability of these wafers.

As the demand for precise timing and frequency control continues to grow, especially with the advent of MEMS (micro electro mechanical systems) and NEMS (nano electro mechanical systems) technologies, quartz crystal wafers remain at the forefront of innovation, playing a vital role in the advancement of modern electronics.

Fused silica， also known as fused quartz, is a glass made from silica (silicon dioxide, SiO2) that has been melted and re-solidified. It is a highly pure form of glass, with very low levels of impurities, and has a number of unique properties that make it useful in a variety of applications.

One of the most important properties of fused silica is its high transparency, which allows it to be used in applications where light transmission is important. It is often used in optical components, such as lenses and windows, because it has excellent optical clarity and low optical distortion.

Another important property of fused silica is its resistance to thermal shock. It can withstand sudden changes in temperature without cracking or breaking, making it useful in applications where temperature changes are common, such as in high-temperature furnaces or in laser optics.

Fused silica also has good chemical resistance, being inert to most acids and alkalis. This makes it suitable for use in harsh chemical environments, such as in the processing of acids or alkalis.

Due to its unique properties, fused silica has a wide range of applications. It is used in scientific instruments, such as spectroscopes and microscopes, where high optical clarity is essential. It is also used in the manufacture of high-performance optical fibres and in the processing of semiconductors, where its resistance to thermal shock and chemical corrosion is beneficial.
