Quartz material porous long strip plate

Quartz material porous long strip plate is a type of porous structural plate made by sintering high-purity natural quartz or synthetic quartz raw materials through special processes. Its unique elongated design and controllable porosity make it outstanding in fields such as high-temperature filtration, gas distribution, semiconductor diffusion, and chemical catalytic support. It also has excellent acid and alkali resistance, thermal stability, and mechanical strength, making it a key consumable in high-end industrial processes worldwide.

Frequently Asked Questions (FAQ)

Q1: My high-temperature process requires a carrier that can withstand temperatures above 1100 ℃ while ensuring uniform gas passage. Ordinary ceramic plates are prone to cracking, but can quartz porous plates solve this problem?

A: Absolutely possible. Our quartz porous strip plate has an extremely low coefficient of thermal expansion and can operate stably for a long time at temperatures of 1200 ℃ or even higher without deformation or explosion. Its uniform microporous structure ensures the ultimate uniformity of airflow distribution, completely solving the problem of traditional materials becoming ineffective at high temperatures.

Q2: We need to deal with highly corrosive chemical liquids or gases, and we are concerned about the material being corroded and contaminating the product. What is the corrosion resistance of this plate?

A: Quartz material inherently possesses excellent acid resistance (except for hydrofluoric acid), and has extremely strong resistance to the vast majority of strong acids, strong oxidants, and organic solvents. By using our porous plates, secondary contamination caused by container corrosion can be eliminated, ensuring that your final product purity meets semiconductor or pharmaceutical grade standards.

Q3: Our device has a special cavity size, and standard parts on the market cannot be installed. Can you provide customized services?

A: We specialize in customized foreign trade services and can flexibly customize the length, width, thickness, porosity (from micrometer to millimeter level), and pore distribution of long strip plates according to your drawings or specific parameters, perfectly adapting to various non-standard equipment without requiring you to modify the production line design.

Q4: As a global purchaser, how can we ensure the quality stability between batches and the timeliness of supply?

A: We have fully automated production lines and a strict ISO quality management system. Each sheet undergoes comprehensive testing for pore size distribution, air permeability, flexural strength, etc., to ensure zero difference between batches. Relying on a mature foreign trade logistics system, we can deliver goods to any port worldwide on time.

Product Core Advantage: Why Choose Quartz Porous Structure?

High Purity: The raw material SiO ₂ content is ≥ 99.99%, and the metal impurity content is extremely low (Fe, Al, Na, K, etc.<1ppm), effectively avoiding the precipitation of impurities at high temperatures or in chemical reactions. It is particularly suitable for semiconductor diffusion, photovoltaic crystal pulling, and high-purity reagent filtration.

Excellent thermal stability: softening point up to 1730 ℃, long-term use temperature can reach 1100 ℃ -1200 ℃. Its coefficient of thermal expansion is extremely low (5.5 × 10 ⁻⁷/℃), which can withstand severe thermal shock without cracking, significantly extending its service life.

Controlled Pore Structure: Using advanced pore forming agent technology and precision sintering process, the pore size range can be precisely controlled from 0.5 μ m to 50 μ m, and the porosity is controlled between 30% -60%, balancing high permeability and high mechanical strength.

Excellent chemical inertness: except for hydrofluoric acid and hot phosphoric acid, it does not react with any acids, bases, or organic solvents, making it an ideal filtering and supporting material in highly corrosive environments.

Typical application scenarios

Semiconductor manufacturing: used as a wafer carrier boat partition in a diffusion furnace and a gas distribution plate in a CVD reaction chamber to ensure uniform flow of doping gas through the wafer surface.

Photovoltaic industry: Breathable bricks in monocrystalline silicon/polycrystalline silicon ingot furnaces, used for uniform introduction of argon gas protective atmosphere to improve the quality of crystal growth.

Chemical and Environmental Protection: High temperature flue gas dust removal filter elements, catalyst carrier support plates, strong acid liquid filter plates.

Metallurgy and Heat Treatment: Pad plates and breathable bases for high-temperature sintering furnaces, used for atmosphere protection during powder metallurgy sintering processes.

Laboratory equipment: Combustion tube support in precision analytical instruments, acid solution aerator.

Customer Application Case Record

Case 1: A leading semiconductor equipment manufacturer in Europe - solving the problem of diffusion uniformity

Customer Requirement: During the development of a new generation 12 inch wafer diffusion furnace, the customer discovered microcracks in the gas distribution plate made of alumina material after long-term operation at 1150 ℃, resulting in uneven distribution of doping gases and significant fluctuations in wafer yield. We urgently need an alternative material that is resistant to high temperatures, highly airtight, and has uniform pore size.

Solution: Our technical team closely collaborates with our engineering department to provide a quartz porous strip plate solution with a SiO ₂ content of 99.995%. We have customized a special plate with a pore size of 5 μ m ± 1 μ m and a porosity of 45%, and carried out special surface acid washing treatment to remove potential surface contamination.

Final effect: After 6 months of continuous operation, the new plate showed no deformation or cracks, the uniformity of gas flow rate increased by 35%, and the within wafer non uniformity decreased by 20%, directly helping the customer improve the production line yield. The customer subsequently signed an annual framework procurement agreement.

Case 2: North American Large Chemical Enterprise - Breakthrough in Filtration under Strong Acid Environment

Customer requirement: A chemical plant engaged in rare metal extraction requires solid-liquid separation in a concentrated sulfuric acid environment at 80 ℃. Traditional polypropylene filter plates are not temperature resistant, while ordinary ceramic filter plates have a lifespan of only 2 weeks under strong acid erosion, and there is a risk of iron ion precipitation contaminating the product.

Solution: We recommend high-density quartz porous long strip plate with a customized thickness of 30mm to enhance compressive strength, and a pore size set at 15 μ m to match its particle size. At the same time, a special-shaped long strip plate with a T-shaped slot was designed for its special groove structure, making it easy to install and fix.

Final effect: The quartz plate remains intact even after continuous use in a strong acid environment for more than 1 year, without any metal ion precipitation detected. The product purity has increased from 99.9% to 99.99%. Customer maintenance costs have been reduced by 80%, and the frequency of production shutdowns and replacements has been significantly reduced.
