Vacuum furnace quartz heating tube is a key electric heating element that works in high temperature, vacuum or protective atmosphere environments. With high-purity fused silica tube as the matrix, it provides a pure, efficient and reliable heat source solution for high-end heat treatment process by virtue of excellent thermal, electrical and chemical stability.
Core product advantage: Why choose quartz heating tube?
The core competitiveness of quartz heating tubes in vacuum furnaces lies in the uniqueness of their materials and structures, with the main advantages reflected in:
1. Excellent thermal stability and high temperature resistance
Extremely high temperature resistance: It can withstand working temperatures of up to 1200 ℃ in the short term and work stably in the range of 1000-1150 ℃ in the long term. Its coefficient of thermal expansion is extremely low, and it can withstand severe thermal shocks without breaking.
Rapid thermal response: Quartz glass has a small thermal inertia and a fast heating rate, which can achieve rapid increase and precise control of process temperature, which is conducive to improving production efficiency and process consistency.
2. Excellent optical and radiation properties
High infrared emissivity: Quartz tubes can emit a high proportion of infrared radiation at high temperatures, achieving efficient non-contact radiation heating with high thermal efficiency and good temperature uniformity inside the furnace.
Excellent spectral transparency: Transparent or semi transparent quartz tubes provide irreplaceable convenience for specific processes that require light wave assisted heating or monitoring, such as certain semiconductor processes.
3. Excellent chemical purity and stability
High purity and pollution-free: Made of high-purity quartz sand, it will not release metal ions or other impurities at high temperatures, ensuring the purity of the vacuum environment and avoiding contamination of heat-treated workpieces (such as semiconductor materials and high-purity metals).
Excellent corrosion resistance: It has good corrosion resistance to most acids (except hydrofluoric acid and hot phosphoric acid) and halogens such as chlorine and bromine, and is suitable for process environments with complex atmospheres.
4. Good electrical insulation and mechanical properties
High insulation strength: It can maintain good electrical insulation performance at high temperatures, ensuring the safe and stable operation of the equipment.
Structural stability: Despite being a brittle material, a well-designed quartz tube, when installed and used correctly, has sufficient mechanical strength to withstand the stress during furnace operation.
Main application areas
Vacuum furnace quartz heating tube is an indispensable component in the following high-end manufacturing and scientific research fields:
Semiconductor industry: drawing and diffusion of monocrystalline silicon and polycrystalline silicon, annealing during chip packaging process.
Aerospace: Vacuum brazing, sintering, and heat treatment of high-temperature alloys and titanium alloys.
New material research and development: sintering of carbon fiber, graphitization treatment, and ceramic materials such as silicon nitride and aluminum oxide.
Photovoltaic industry: PECVD, diffusion furnace and other process links in the manufacturing of solar cells.
High end lighting: sealing and exhaust of electric light source products such as metal halide lamps and xenon lamps.
Research experiments: High temperature vacuum experimental furnaces used in universities and research institutes for materials science and physical chemistry research.
The customized services we can provide
To meet the specific needs of different equipment and processes, we provide comprehensive professional customization services:
1. Customization of size and shape: Different diameters (Φ 20mm - Φ 100mm+) and lengths (100mm -2000mm+) of straight, U-shaped, W-shaped or other shaped quartz heating tubes can be customized according to the furnace structure of the customer's vacuum furnace.
2. Surface coating treatment: Provide a "milky white quartz" treatment to transform the surface of the transparent quartz tube into a uniform milky white color, which can significantly improve infrared radiation efficiency, make heating more uniform, and shield internal heating wires, extending their lifespan.
3. Customization of electrodes and connection methods: Multiple materials of electrode caps (such as molybdenum foil, stainless steel) and connection structures (such as threads, flanges) are provided to ensure perfect matching and vacuum sealing with the customer's furnace body.
4. Technical parameter matching: Based on the maximum operating temperature, power density, and voltage (such as 220V, 380V) required by the customer, accurately design the material (iron chromium aluminum, nickel chromium alloy, molybdenum, tungsten, etc.) and winding method of the resistance wire to achieve the optimal balance between energy efficiency and lifespan.
What key problems can quartz heating tubes solve for you?
Choosing high-performance quartz heating tubes is a direct and effective solution to address the pain points in the following industries:
Solving the "pollution" problem: replacing ordinary metal heating tubes fundamentally avoids the pollution of high-value workpieces caused by metal element volatilization in high-temperature vacuum environments, ensuring product purity and performance.
Solving the problem of "uneven temperature and inaccurate temperature control": With fast thermal response and high infrared radiation, a faster and more uniform temperature field distribution in the furnace has been achieved, improving the consistency of heat treatment processes and product yield.
Addressing the issue of low equipment reliability: Excellent thermal shock resistance and chemical stability significantly reduce unplanned shutdowns caused by heating element rupture, oxidation, or corrosion, improving the operational reliability and service life of the vacuum furnace.
Addressing the issue of "inability to achieve special processes": Its transparency and high temperature resistance make it possible for advanced processes that rely on photothermal composites or extreme high temperatures, driving the development of new materials and technologies.
The quartz heating tube of a vacuum furnace is far from a simple consumable, it is the core technical component that determines the upper limit of the performance of vacuum heat treatment equipment. Its superior comprehensive performance has placed it in an irreplaceable position in the industrial and scientific research fields that pursue high precision, high purity, and high reliability.
