Long term high-temperature tolerance of 1100 degrees quartz tube is a high-performance special quartz glass product, made of high-purity quartz sand (SiO ₂ content ≥ 99.99%) melted at high temperature and precision drawn. This product has excellent high temperature resistance and can work stably for a long time in a high temperature environment of 1100 ℃. At the same time, it has excellent thermal stability, low thermal expansion coefficient, high transmittance (UV to infrared band), and excellent corrosion resistance (acid, alkali, and most chemical reagents erosion).  

FAQ—Frequently Asked Questions

Q: What are the key advantages of this quartz tube under operating conditions of 1100°C?

A: Its key advantages lie in its extremely low hydroxyl content (controllable to below 10 ppm) and highly dense glassy structure. This allows it to maintain an extremely low crystallization rate even during prolonged exposure to high temperatures, effectively preventing tube embrittlement, cracking, and reduced light transmittance caused by crystallization, resulting in a service life far exceeding that of ordinary quartz tubing.

Q: What key dimensional parameters can be customized for this product?

A: We offer highly flexible customization services. The outer diameter ranges from 1.5 mm to 300 mm and even larger diameters; wall thickness can be adjusted as needed within the range of 0.5 mm to 30 mm; and lengths can be customized to non-standard specifications ranging from 10 mm to over 3,000 mm. We can accommodate everything from micro-reaction tubes to large furnace tubes.

Q: How chemically stable is this quartz tube in different process atmospheres?

A: Except for hydrofluoric acid and hot phosphoric acid above 300°C, this material is chemically inert to the vast majority of acids, halogens, and neutral salts. In high-temperature processes such as diffusion and oxidation, it effectively blocks the migration of impurity ions, ensuring the cleanliness of the process chamber.

Core advantages

Ultra high temperature tolerance: Long term stable working temperature up to 1100 ℃, short-term can withstand high temperature up to 1300 ℃ (such as experimental or special process requirements).  

Low thermal expansion: The coefficient of thermal expansion is extremely low (5.5 × 10 ⁻⁷/℃), avoiding rupture caused by sudden temperature changes.  

High purity material: no bubbles, no impurities, reducing the risk of pollution in high-temperature environments.  

Customized design: supports customization of various sizes, shapes (straight pipes, bent pipes, irregular pipes), wall thicknesses, and surface treatments (frosted, coated, etc.).  

Application

1. High temperature experimental and scientific research equipment

-Used for muffle furnace, tube furnace, CVD (chemical vapor deposition) equipment, as a reaction chamber or sample carrier tube.  

-Solve the problems of ordinary glass tubes being prone to softening and deformation, and metal tubes contaminating samples.  

2. Semiconductor and Photovoltaic Industry

-As a carrier tube for wafer processing and diffusion furnaces, it is heat-resistant and does not affect the purity of silicon wafers.  

-Suitable for gas delivery pipelines in LED/MOCVD processes.  

3. Optoelectronics and Laser Technology

-High transparency makes it an ideal packaging material for high-power lasers and ultraviolet lamps.  

4. Chemical and environmental protection fields

-High temperature reaction pipelines used for corrosive gases such as chlorine and fluorine, replacing metal or ceramic pipes that are prone to aging.  

5. New energy and battery materials

-High temperature sintering tubes for lithium positive electrode materials and solid-state battery research and development ensure no impurity interference.  

Customized service

We provide comprehensive customized solutions to meet the special needs of different industries:

Value: Solving User Challenges

Addressing Structural Failure at High Temperatures: During continuous operation at temperatures exceeding 1,100°C, ordinary glass tubes are prone to softening and deformation. With a softening point as high as 1,730°C, this product maintains stable performance over extended periods of use, preventing emergency furnace shutdowns caused by tube collapse.

Mitigating the Risk of Process Contamination: Given the extreme sensitivity of the semiconductor and photovoltaic industries to trace impurities, this product achieves a purity of over 99.99%, effectively preventing the release of alkali metals (such as K and Na) and transition metals into the process atmosphere, thereby ensuring product yield.

Overcoming Thermal Shock Breakage: To address the challenges posed by frequent temperature cycling during the process, the quartz tube’s extremely low coefficient of thermal expansion provides exceptional resistance to thermal shock. Even when transferred directly from a high temperature of 1,100°C into cold water, the tube will not shatter.
