12-14mm thick transparent quartz plate

12-14mm thick transparent quartz plate is mainly made of high-purity quartz, which has excellent transparency, high temperature resistance, and corrosion resistance. It has strong hardness, wear resistance, acid and alkali resistance, and is suitable for high temperature, corrosion resistance, and optical fields. The common thickness is 12-14mm, but in actual production it may be 13.5mm or 14mm. This product also has high insulation and waterproof anti slip performance, and can be used for partitions, ceilings, and walls in laboratories, hospitals, and other places to ensure a clean and durable environment.

Core features include:

Excellent optical performance: with a transmittance of over 93% in the spectral range from ultraviolet (160nm) to infrared (5 μ m), and a transmittance of over 80% in the ultraviolet region, it can meet the stringent requirements for light purity in semiconductor lithography, optical instruments, and other fields.

Extremely strong temperature resistance: the softening point temperature reaches 1730 ℃, which can be used for a long time at 1100 ℃, and the short-term temperature tolerance can reach up to 1450 ℃, suitable for high-temperature experimental environments.

Excellent chemical stability: except for hydrofluoric acid and phosphoric acid, it hardly reacts with any acid, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, which can avoid material failure caused by chemical corrosion.

Outstanding thermal stability: The coefficient of thermal expansion is extremely low, and the board will not explode when heated to 1100 ℃ and placed in room temperature water, solving the problem of cracking caused by sudden temperature differences in traditional glass.

Excellent electrical insulation performance: The resistance value is 10000 times that of ordinary glass, and it can maintain insulation even in high temperature environments, making it suitable for power equipment protection.

Core application scenario: Efficient solution to industry pain points

（1） Semiconductor Manufacturing: Wafer Carrier and Photolithography Protective Film

Problem: Semiconductor processing needs to be carried out in a high temperature environment above 1000 ℃, and traditional materials are prone to deformation or release impurities to contaminate the wafer.

Solution: 12-14mm thick quartz plate has become the preferred material for wafer carrier boats and diffusion furnace core tubes due to its high temperature resistance and low impurity characteristics. For example, after a domestic semiconductor company adopted customized quartz plates, the wafer yield rate increased by 12% and the equipment maintenance cycle was extended by three times.

（2） Fiber optic communication: prefabricated rods and core components of wire drawing furnaces

Problem: Fiber optic transmission relies on the principle of total internal reflection, requiring materials with extremely low and uniform refractive index.

Solution: The refractive index of quartz glass is only 1.46, the absorption coefficient is less than 0.001, and the thickness of 12-14mm can meet the mechanical strength requirements of fiber preform rods and furnace core tubes. After a certain fiber optic manufacturer used this thickness of quartz plate, the fiber attenuation rate decreased to 0.18dB/km, reaching the international advanced level.

（3） Photovoltaic industry: quartz crucible and diffusion furnace tube

Problem: Polycrystalline silicon melting requires a high temperature of over 1400 ℃, and traditional crucibles are prone to releasing metal ions to contaminate the silicon material.

Solution: The crucible made of high-purity quartz plate can withstand more than 200 cold and hot cycles, with a metal impurity content of less than 0.01ppm. After being applied by a certain photovoltaic enterprise, the cost of drawing monocrystalline silicon rods decreased by 18%, and the conversion efficiency of solar cells increased by 0.3%.

（4） Optical Instruments: Lens and Window Materials

Problem: Astronomical telescopes, lasers, and other equipment require materials with high transmittance and minimal thermal deformation over a wide frequency range.

Solution: 12-14mm thick quartz plates can be processed into lenses or windows with a diameter of 500mm, meeting the requirements of F/1.2 large aperture optical systems. After being used by a certain observatory, the distortion rate of observed images decreased from 0.5% to 0.1%.

（5） Electric light source field: special lighting and ultraviolet curing

Problem: Automotive xenon lamps and medical ultraviolet lamps require materials that are resistant to high temperatures and UV aging.

Solution: Quartz plates can withstand power densities of over 3000W/cm ⊃2; and have a service life of over 10000 hours. After being adopted by a certain automotive lighting manufacturer, the product warranty period has been extended from 2 years to 5 years.

Customized service

（1） Customization of size and shape

Standard specifications: Width 150-320mm, length 1240-1600mm, thickness 12/14mm ± 0.2mm.

Irregular machining: supports cutting of complex geometric shapes such as circular (maximum diameter 500mm), square (700 × 700mm), and circular, with hole accuracy of ± 0.05mm.

Case: Customized a circular quartz plate with a diameter of 300mm and a central aperture of 50mm for a research institution, to be used in plasma experimental equipment.

（2） Surface treatment process

Polishing grade: Provides single-sided/double-sided polishing, with a surface roughness Ra ≤ 0.5nm, meeting the requirements of optical interferometers.

Coating service: It can use anti reflective film (AR), reflective film (HR) or spectral film to increase the transmittance of specific wavelength bands to 99.5%.

Case: After coating a 1064nm wavelength anti reflective film for a certain laser enterprise, the output power of the laser increased by 15%.
