As a quartz products manufacturer with many years of professional experience, we are well aware of the crucial role of large-diameter tube furnace quartz tubes in high-end industrial and scientific research fields. It is not only a reaction vessel, but also a core component that determines the process limit, safety and final outcome. We focus on manufacturing large-diameter, high-performance quartz tubes, providing reliable core consumables for industrial and scientific research customers worldwide.
Core product advantage: Why do our quartz tubes stand out
Our high-purity large-diameter quartz tubes are not merely containers but also a guarantee of craftsmanship. Its outstanding performance is reflected in the following aspects:
1. Outstanding thermal stability and high-temperature resistance: Made of high-purity natural quartz sand, with a softening point as high as 1780℃, and a long-term service temperature up to 1200℃. During repeated rapid heating and cooling processes, it exhibits an extremely low coefficient of thermal expansion, effectively resisting thermal stress cracking and ensuring process safety.
2. Extremely high chemical purity and stability: The hydroxyl content of quartz tubes is extremely low (< 3ppm), and the content of heavy metal impurities is less than 50ppm. This means that it will not contaminate the materials inside the furnace at high temperatures, making it an ideal choice for applications with strict purity requirements such as semiconductor wafers and sintering of high-purity materials.
3. Excellent optical performance: It features an extremely high UV-infrared transmittance, making it particularly suitable for special process scenarios that require photocatalysis, UV curing or infrared heating, ensuring efficient and uniform energy transfer.
4. Precise dimensional and geometric tolerances: We possess mature precision control technology and are capable of manufacturing quartz tubes with diameters ranging from 100mm to 500mm or even larger. The pipe wall thickness is uniform, and the straightness and roundness have been strictly calibrated to ensure a perfect match with the furnace body and flange, avoiding leakage or damage caused by improper installation.
5. Outstanding anti-crystallization performance: Through advanced process control, our quartz tubes have a stronger anti-crystallization (loss of transparency) ability at high temperatures, significantly extending the product's service life in harsh environments and reducing the total cost of ownership for customers.
Main application fields
Our products are widely used in the following cutting-edge technologies and industrial fields:
Semiconductor manufacturing: used in wafer oxidation, diffusion, annealing and CVD (Chemical Vapor Deposition) processes.
Photovoltaic energy: Sintering and passivation of solar cells (such as PERC, TOPCon).
Materials Science: Synthesis and sintering of nanomaterials, graphene, and carbon nanotubes, as well as high-temperature treatment of ceramic and powder metallurgy materials.
Chemistry and chemical engineering: As a fixed-bed reactor, it is used for catalyst evaluation, organic synthesis, etc.
Universities and research institutes: Provide stable and reliable experimental platforms for various cutting-edge material research.
The key problems we can solve
By choosing our large-diameter quartz tubes, you will effectively avoid the following common pain points:
Solve pollution problems: Eliminate batch product contamination caused by impurities precipitating from quartz tubes to ensure product yield.
Avoid cracking risks: Excellent thermal shock resistance, capable of handling complex temperature rise and fall processes, reducing unexpected shutdowns and production losses.
Enhance process uniformity: Precise geometric dimensions and excellent thermal field distribution ensure the uniformity and stability of the temperature field and atmosphere field inside the furnace tubes.
Extending equipment lifespan: The high anti-crystallization property means a longer replacement cycle, reducing spare parts inventory and maintenance costs.

Strict quality control: From raw materials entering the warehouse to finished products leaving the factory, every process undergoes strict inspection, including size inspection, pressure testing and purity analysis, to ensure that each quartz tube has outstanding performance.
Competitive prices: Large-scale production and an optimized supply chain enable us to offer highly competitive prices in the market without sacrificing quality.
Real customer cases (anonymous
Case One: A certain European photovoltaic research institute
Requirement: A quartz tube with a diameter of 300mm, featuring three symmetrical side tubes and a custom water-cooled flange is needed for the research and development of the new TOPCon battery technology.
Challenge: The structure is complex, with extremely high requirements for the Angle and concentricity of the branch pipes. Many suppliers are unable to meet the precision requirements.
Our solution: Our engineers have conducted multiple technical exchanges with the client, precisely modeled, and successfully manufactured products that fully meet the requirements through special processing fixtures. The customer reported that the quartz tube was installed smoothly and had perfect air tightness, providing crucial support for their R&D project.
Case Two: A certain North American semiconductor equipment manufacturer
Demand: To find a stable supplier of large-diameter quartz tubes (Ø400mm x 2000mm) for its new vertical diffusion furnace, with extremely high purity and anti-crystallization ability required.
Challenge: The quartz tubes previously used by the customer experienced local crystallization after continuous operation for several months, which led to the need for frequent replacement and affected production capacity.
Our solution: We recommended a low crystallization grade quartz tube with a special process for it. After being put into use, under the same process conditions, its service life has been extended by more than 40% compared with the products of the original supplier. The customer is very satisfied with this and has listed us as a qualified supplier.
