Solid transparent quartz ingot

Solid transparent quartz ingot is a dense and bubble free optical substrate made of high-purity silicon dioxide with a purity of 99.99% or higher through electric melting or gas refining processes. It has excellent ultraviolet transmittance, extremely low thermal expansion coefficient, and excellent chemical stability, making it an indispensable core material in the fields of semiconductor lithography, laser optics, and aerospace.

User Core Concerns: FAQ Quick Questions and Answers

Q: Can this quartz ingot solve the optical loss problem caused by insufficient purity of my raw materials?

A: Absolutely possible. Our solid transparent quartz ingots are controlled at ppb levels of metal impurities through advanced purification processes, significantly reducing light absorption and scattering, ensuring maximum efficiency of high-energy laser transmission.

Q: My device needs to operate under extreme temperature differences. What should I do if ordinary quartz easily explodes?

A: This product has an extremely low coefficient of thermal expansion (about 0.55 × 10 ⁻⁶/℃) and can withstand rapid thermal shocks from 1100 ℃ to room temperature without breaking, perfectly solving the structural stability problem in high-temperature environments.

Q: We need special sizes or irregular cutting. Can the manufacturer provide customized services?

A: Support comprehensive customization. Whether you need extra large diameter ingots or bars with specific aspect ratios, we can provide a one-stop solution from blank forming to precision grinding based on drawings.

Core application areas

Solid transparent quartz ingots, as the base material, are widely used in the following high-precision and cutting-edge fields after subsequent processing:

Semiconductor manufacturing: used for photolithography optical system lenses, diffusion furnace core rods, wafer carriers.

Laser optics: high-power laser window plate, reflector substrate, fiber preform core rod.

Aerospace: missile fairing, space telescope mirror substrate, high temperature resistant observation window.

Photovoltaic energy: crucible lining material for single crystal silicon drawing, diffusion process carrier.

Research and testing: UV spectrophotometer colorimetric dish substrate, synchrotron radiation light source component.

Six major product advantages

Ultra high purity: SiO ₂ content ≥ 99.99%, total metal impurities<20ppm, ensuring uniform optical performance.

Excellent transparency: It has extremely high transmittance in the 185nm-2500nm wavelength range, especially adept at deep ultraviolet (DUV) transmission.

Heat resistance and impact resistance: The softening point is as high as 1730 ℃, and it can work in an environment of 1100 ℃ for a long time. Its thermal shock resistance is tens of times better than ordinary glass.

Chemical inertness: Resistant to almost all strong acid and alkali corrosion except hydrofluoric acid and hot phosphoric acid, suitable for harsh chemical environments.

Electrical insulation: It maintains extremely high electrical resistivity at high temperatures and is an ideal high-temperature insulation material.

No bubble defects: Using vacuum melting or plasma refining technology, there are no visible bubbles inside, and the stripe degree is extremely low.

Customer Application Case Record

Case 1: European semiconductor equipment giant upgrades lithography machine lens substrates

Customer pain point: When developing a new generation ArF excimer laser lithography system, the customer found that the quartz substrate provided by the original supplier had a trace absorption peak at a wavelength of 193nm, which caused thermal deformation of the lens after long-term operation and affected imaging accuracy.

Solution: Our technical team is involved and recommends using "low hydroxyl synthetic quartz ingots". By adjusting the gas refining process parameters, the OH content is precisely controlled at<5ppm, and the annealing curve is optimized to eliminate internal stress. We provide high uniformity blanks with a diameter of 280mm × 400mm and cooperate with customers for double-sided ultra precision polishing pretreatment.

Final effect: After testing, the transmittance of the new material at 193nm has been increased to over 99.95%, and the thermal lens effect has been reduced by 60%. The customer's equipment has successfully passed the 7nm process validation and signed an annual strategic procurement agreement with us.

Case 2: A high-power laser research institute in North America - Inertial confinement fusion device window

Customer pain point: During the kilojoule level laser fusion experiment, the original quartz window plate experienced microcracks or even explosions under multiple high-energy pulse bombardment, resulting in frequent experimental interruptions and extremely high replacement costs.

Solution: For ultra-high energy density environments, we have customized "no stripes, zero defects" solid quartz ingots. Using special electric melting clarification technology to completely eliminate micron sized inclusions. At the same time, according to the customer's optical path design, the ingot is directly cut into non-standard trapezoidal cross-sections to reduce subsequent processing losses.

Final effect: The new window successfully withstood over 5000 full energy laser pulse impacts without damage, ensuring the continuity of the experiment. The customer's evaluation of our product's reliability under extreme physical conditions is impressive.

Case 3: A leading photovoltaic enterprise in Asia - Extended service life of thermal field components for monocrystalline furnaces

Customer pain point: During the process of drawing large-sized (12 inch) monocrystalline silicon rods, the inner lining of the quartz crucible softens and deforms too quickly due to high temperature, resulting in a short operating cycle of the monocrystalline furnace and frequent shutdowns for replacement, seriously affecting production capacity.

Solution: We have developed high viscosity, high-strength solid quartz rods as reinforcement skeleton materials for it. By doping with trace amounts of alumina, the high-temperature viscosity is increased while maintaining high purity without contaminating the silicon liquid.

Final effect: The continuous operation time of the single crystal furnace has been extended by 15%, the crucible deformation rate has been reduced by 40%, and millions of dollars in downtime maintenance costs and consumables expenses have been saved for customers every year.
