99.99% purity opaque quartz tube is a special material made of high-purity silicon dioxide, featuring excellent high-temperature resistance (long-term 1100℃), corrosion resistance (except for hydrofluoric acid), thermal stability and electrical insulation performance. The surface is milky white, with low light transmittance but good heat insulation. It is widely used in semiconductors, photovoltaics, heating tubes, laboratory instruments and high-temperature industrial equipment, and is suitable for harsh environments that require no pollution, acid and alkali resistance and extreme temperatures.
As a globally leading manufacturer of custom quartz products, we deeply understand the crucial impact of material purity and performance on your process flow.
Core product advantage: Why choose 99.99% purity opaque quartz tubes?
Our opaque quartz tubes are made from carefully selected high-purity natural quartz sand through an advanced arc melting process. Its "opaque" feature stems from the numerous tiny bubbles densely distributed within the material, which can scatter light extremely effectively, thus bringing unique product advantages:
Ultimate high-temperature stability: Softening point as high as 1270°C, long-term service temperature up to 1100°C. Even under severe temperature fluctuations, it can still maintain excellent thermal shock resistance and structural integrity, far exceeding ordinary transparent quartz tubes or ceramic materials.
Outstanding heat insulation performance: The internal micro-bubble structure forms an excellent insulation layer, which can effectively reduce heat loss in the furnace, significantly improve energy utilization efficiency, and lower operating costs.
Extremely high chemical purity (99.99%) : The SiO₂ content is no less than 99.99%, and the content of key impurities such as alkali metals (K, Na, Li) and heavy metals is extremely low. This ensures that in sensitive processes such as semiconductors and photovoltaics, the products will not be contaminated by impurities precipitated from the pipes.
Outstanding structural strength: Compared with transparent quartz tubes, opaque quartz tubes have higher mechanical strength and anti-deformation ability, and a longer service life, especially performing outstandingly in environments carrying heavy workpieces or subjected to mechanical stress.
Main application fields: Which core problems in which industries are being solved?
This high-performance material is an indispensable component in multiple high-end industrial fields, mainly addressing three core issues: pollution, energy consumption, and device lifespan in high-temperature environments.
1. Semiconductor and photovoltaic industry:
Solution: Prevent metal ion contamination in high-temperature diffusion and oxidation processes.
Application: Widely used in Wafer boats, diffusion furnace tubes, core tubes for CVD processes, etc. Its high purity ensures that the silicon wafers remain uncontaminated in an environment up to 1200°C.
2. Metallurgy and Heat Treatment industry:
Solution: Provide a uniform and clean high-temperature environment to extend the service life of the furnace body.
Application: It is used as the furnace chamber and lining of high-temperature sintering furnaces, brazing furnaces and annealing furnaces. The excellent heat insulation property keeps the surface temperature of the furnace body lower, making the working environment safer and saving energy and reducing consumption at the same time.
3. Optoelectronics and New Materials Industry
Solution: Provide stable reaction vessels for the synthesis of new materials such as LED sapphire substrates and phosphors.
Application: As a sintering pad, crucible and reaction tube, it maintains dimensional stability at high temperatures and does not react with the treated material.
4. Laboratory and Scientific Research Equipment
Problem-solving: Provide reliable and durable high-temperature environment carriers for scientific research experiments.
Application: It is used for the furnace tubes and accessories of muffle furnaces, tube furnaces and carbon determination furnaces, meeting the strict requirements of scientific research for the consistency and repeatability of experimental conditions.
Our customized services: Beyond standards, meeting individual needs
We are well aware that reference standards often fail to fully match complex practical applications. Therefore, we offer comprehensive and in-depth customization services
Size customization: We can precisely customize the outer diameter, inner diameter, length, wall thickness and other dimensions according to your equipment drawings.
Shape customization: Supports the production of complex geometric shapes such as square tubes, special-shaped tubes, flanged tubes, and end caps.
Surface treatment: We offer end face treatments such as grinding, polishing, and flame treatment to ensure the airtightness and flatness of the installation.
Precision processing: It can perform secondary precision processing such as cutting, drilling and slotting, achieving perfect integration with your equipment.
Real customer cases bear witness
Case One (A well-known photovoltaic research institute in Europe) :
Requirement: A diffusion furnace tube that can operate for a long time at 1150°C and does not contaminate N-type silicon wafers is needed.
Solution: We customized 99.99% purity opaque quartz tubes with specially treated inner walls for them and optimized the tube wall thickness to balance strength and thermal efficiency.
Result: The customer reported that after more than six cycles of use, there were no signs of deformation on the quartz tube, the minority carrier lifetime data of the silicon wafer remained stable, and the process consistency was significantly improved.
Case Two (A large metal Heat treatment company in Asia) :
Requirement: Replace the original ceramic furnace chamber to solve the problems of easy cracking and high energy consumption.
Solution: We designed and manufactured a set of combined opaque quartz furnace lining.
Result: The surface temperature of the furnace body dropped by more than 50°C, energy was saved by approximately 18%, and the service life of the furnace lining is expected to be extended by more than three times, significantly reducing the maintenance costs and downtime for customers.
