High purity fused quartz crucible
The high-purity fused quartz crucible is a core container made of high-purity quartz sand (SiO ₂ content ≥ 99.99%) through high-temperature melting, precision molding and special post-treatment processes. Its core advantage lies in its excellent thermal stability, chemical inertness, and low thermal expansion coefficient, which can maintain structural stability in extreme temperature environments (0-1600 ℃). It is an irreplaceable key consumable in fields such as semiconductors, photovoltaics, and precision casting.
Core Features
Ultra pure material: impurity content less than 100ppm, avoiding metal ion pollution and meeting semiconductor grade cleanliness requirements.
Heat shock resistance: able to withstand rapid cooling and heating (Δ T ≤ 300 ℃/s), reducing the risk of cracking caused by thermal stress.
Corrosion resistance: It has extremely strong resistance to strong acids (except HF), strong bases, and molten metals, extending its service life.
High transmittance: The transmittance in the ultraviolet to infrared band is greater than 90%, suitable for melting optical materials.
Customized design: supports personalized customization of shape, size, wall thickness, and surface treatment (such as polishing and coating).
Typical application scenarios
（1） Semiconductor industry
Monocrystalline silicon growth: As the core container of Czochralski method (Czochralski method) single crystal furnace, it carries the process of polycrystalline silicon melting, ensuring that the purity of silicon crystals reaches 9N or above.
Compound semiconductor: used for melting III-V compounds such as GaAs and InP to avoid lattice defects caused by the introduction of metal impurities.
Epitaxial deposition: As a reaction chamber for MOCVD (Metal Organic Chemical Vapor Deposition), it ensures the uniformity of the thin film.
Addressing pain points: replacing traditional graphite crucibles, eliminating carbon pollution risks, and improving wafer yield by 15% -20%.
（2） Photovoltaic industry
Polycrystalline silicon ingot: It carries silicon material in directional solidification method and achieves low defect rate silicon ingot production through precise temperature control.
PERC cell preparation: As a diffusion furnace quartz boat, it can withstand high temperature phosphorus diffusion process and reduce glass layer detachment.
Addressing pain points: Extend the service life of the crucible to over 200 times and reduce the cost per watt by 0.03 yuan.
（3） Precision casting and special alloys
Titanium alloy melting: Carrying active metals such as titanium and zirconium in a vacuum arc furnace to avoid reaction with crucible materials.
Optical glass forming: used for melting high refractive index materials such as calcium fluoride and germanium glass to ensure optical uniformity.
Addressing pain points: Replacing platinum rhodium alloy crucibles reduces costs by 80% while avoiding precious metal loss and pollution.
（4） Research and Special Experiments
High temperature chemical reaction: As an inner lining of an autoclave, it can withstand extreme pH environments and high-pressure conditions.
Quantum material synthesis: providing atomic level clean surfaces in MBE (molecular beam epitaxy) systems.
Customized service
We are well aware that there are differences in the requirements for crucibles among different customers, equipment, and even processes. Therefore, we provide comprehensive and flexible customization services to ensure that our products perfectly match your production system.
Size customization:
We can customize crucibles with various diameters, heights, bottom shapes (flat bottom, ball bottom), and inclinations according to your furnace model.
We offer a full range of products from small laboratory sizes (such as a few inches) to large industrial sizes (such as 32 inches, 36 inches, and above).
Wall thickness customization:
Provide solutions with different side wall and bottom thicknesses to meet different thermal field design, insulation performance, and mechanical strength requirements.
Coating customization:
Barium/cerium coating on the inner wall: This is a standard option for semiconductor grade crucibles. The coating can form a dense barrier layer at high temperatures, effectively suppressing the reaction and crystallization between the crucible and the silicon liquid, delaying the formation of the quartz layer, greatly extending the service life of the crucible, and reducing silicon liquid pollution.
We can provide coating solutions with different thicknesses and compositions according to your process requirements.
Let us use the extremely pure and stable high-purity fused quartz crucible to become a solid foundation for your high-quality production. Welcome to inquire and cooperate!
Luverre Quartz manufactures and sells a wide range of high quality fused quartz glass, including fused quartz tubes, fused quartz plates, fused quartz rods, fused quartz windows, fused quartz crucibles, fused quartz boats, fused quartz flanges, fused quartz beakers, fused quartz glass instruments, and more.
