Quartz Glass Plate Disc

Quartz glass sheet/plate/disc is a special industrial technical glass made from melting pure natural quartz (such as crystal, quartz sand, etc.). It is usually colorless and transparent, with a visible light transmittance of over 85%, and some products can even reach over 93%.
Quartz glass sheet has excellent heat resistance, light transmittance, electrical insulation, and chemical stability. Its heat resistance is extremely high, with regular use temperatures reaching 1100 - 1200 degrees, and short-term use temperatures reaching up to 1400 or even 1450 degrees.

Quartz glass sheets, due to their high purity, high temperature resistance, low thermal expansion, and excellent optical properties, have irreplaceable application value in multiple high-tech and industrial fields.
1. Semiconductor Manufacturing (Core Application)
As a critical consumable in the semiconductor industry, quartz glass wafers are used in wafer processing for:
Diffuser Tube/Boat Shape/Bell Jar : Carry silicon wafers for high-temperature processes such as doping and oxidation, withstand 1100 degrees for long-term use without contaminating the wafer.
Photoresist Mask Base Plate JGS1 type high-transparency UV characteristics (185-250nm) meet the high-precision requirements of photolithography machines for substrates.
Cleaning Tank/Bracket : Resistant to corrosion from strong acids other than hydrogen fluoride, suitable for wafer etching and ultrasonic cleaning processes.
2. Optical and Optoelectronic Fields
UV-Infrared Optical Components JGS1/JGS2/JGS3 types cover far ultraviolet (185nm), ultraviolet (200nm), and infrared bands respectively, used for lenses, prisms, laser windows, etc.
Optical Fiber Communication As the basic material for fiber optic preform rods, it has a light transmittance of over 90% and stable refractive index, supporting 5G optical network construction.
Precision Instruments Double-sided polished surface roughness [4[9[12<5], used for spectrometer cuvettes, space telescope lenses, etc.
3. Aerospace and Military Industry
Spacecraft Observation Window Resistant to 1730C high temperatures and cosmic ray radiation, used for spaceship windows and solar cell protective covers
Radar Antenna Cover Quartz Fiber Reinforced Composite Material with Low Dielectric Loss Suitable for Fighter Radar Systems
4. Medical and Special Equipment
High Temperature Reaction Window Used as an observation window in chemical equipment, resistant to corrosive gases and rapid temperature changes.
5. Other High-end Applications
Photovoltaic Industry: As a single-crystal silicon growth crucible material, it reduces impurity introduction.
Beauty Instruments: Ultra-thin (0.05mm) filter base material, superior light transmission stability compared to ordinary glass

The application advantages of quartz glass sheets stem from their comprehensive properties: silicon dioxide purity of 99.99%, low thermal expansion coefficient of 5.410/, visible light transmittance exceeding 93%, and can be adjusted to meet different spectral needs through hydroxyl content. With the development of semiconductor and optical communication industries, the market demand will continue to increase.
