Advantages of Quartz Plate
High transparency
Quartz glass exhibits a remarkably high degree of transparency and light transmittance, reaching levels comparable to those observed in optical grade glass, with a transmittance exceeding 90%. These characteristics of quartz glass render it suitable for utilization in the fabrication of optical instruments, laser apparatus, fibre optic communication systems and other fields of advanced technology.
Hightemperature resistance
Quartz glass is characterized by a high melting point, reaching up to 1710 degrees Celsius, and demonstrates excellent high-temperature resistance, which permits its utilization in the fabrication of high-temperature stoves, quartz boats and other equipment capable of withstanding high temperatures.
Corrosion resistance
Quartz glass exhibits excellent corrosion resistance and high resistance to a wide range of acids, alkalis, salts, and other chemicals. This characteristic enables quartz glass products to be used in the fabrication of corrosion-resistant apparatus, including chemical laboratory apparatus and chemical pipes.
High purity
The purity of quartz glass can reach a level exceeding 99.95%, with an extremely low impurity content, which enables quartz glass products to be used in the fabrication of high-purity experimental apparatus and analytical instruments, among other applications.
Good electrical insulation performance
Quartz glass exhibits favourable electrical insulation properties, rendering it suitable for utilization in a multitude of fields, including electronics and electrical appliances.
Application of Quartz Glass Plates
Chemical Industry: Quartz glass does not react with most chemicals and works well in harsh environments. People use it in lab equipment, reaction containers, and industrial pipelines.
Electronics: Electronic devices like clocks, oscillators, and circuit components deliver precise frequency control without draining power.
Environmental Protection: Quartz plates improve the environment by absorbing pollutants During water purification, traditional filter materials are replaced.
Food Industry
Breweries and food processors depend on quartz glass components for filtering, separating ingredients, and keeping contaminants out of production lines.
Medical Tools
Quartz glass is safe for medical use. It is strong and heat-resistant. Medical professionals use it in surgical tools, medical glassware, and measuring instruments.
Optical Devices
Quartz glass can handle high temperatures, are clear, and have a high refractive index. You will find its application in fiber optics, lasers, and sensors.
Semiconductors
Quartz glass is used as a base material for circuits and masking layers in semiconductor chip manufacturing.
Manufacturing and Customization of Optical Quartz Plates
Precision Manufacturing
Optical quartz plates are manufactured with utmost precision, ensuring high dimensional accuracy. They are cut to exact lengths using specialized equipment, resulting in clean and precise edges. Fire polishing further enhances the surface finish, eliminating sharp edges and minimizing light scattering.
Versatile Customization
The versatility of quartz allows for customization in a wide range of shapes and sizes. From rectangular plates to complex geometric configurations, quartz plates can be tailored to meet specific application requirements. This customization ensures optimal performance in optical systems, maximizing light transmission and minimizing distortions.
Tailored Solutions
Through customization, optical quartz plates can be engineered to meet specific wavelength requirements. By controlling the thickness and orientation of the crystal, plates can be optimized for specific optical wavelengths, ensuring maximum transmission and minimizing energy loss.
Quartz Plates Made
Step 1: Cutting
We test raw materials before cutting,
we cut the sizes according to the clients' requirements.
Step 2: Polishing
We have fire polishing and cold polishing.
Cold polishing can remove stress, fire polishing can make the products more clear and bright. At last, we chamfer the edges not to hurt users.
Step 3: Cleaning
We remove the surface impurities and dirt.
Step 4: Quality Control
Before shipping, we control the products quality, make all size tolerances are allowed.
