A 70mm diameter tubular furnace refers to tubular heating equipment with a furnace tube inner diameter of 70mm. It falls into the category of non-standard pressure vessels. 1 Based on function and application, these furnaces can be categorized as conventional atmosphere tubular furnaces, vacuum tubular furnaces, and specialized types (such as sliding and rotary types).

Core Application Areas and Technical Advantages

1. Laboratory Materials R&D
   Nanomaterial Preparation: Such as carbon nanotubes and quantum dots. The 70mm diameter tube is compatible with medium-sized sample holders, meeting the needs of batch experiments.

Fundamental Research on Thin Film Deposition: Combined with plasma modules (such as PECVD), high-quality semiconductor thin films (such as silicon-based thin films and metal oxide thin films) can be deposited at low temperatures.

2. Industrial Pilot and Small-Scale Production
   Ceramics/Powder Metallurgy: The rotary 70mm diameter tube furnace enables continuous sintering of powder materials, improving material uniformity through tilting or rotating structures.
3. Electronic Component Heat Treatment: Used for pre-packaging annealing of sensors and microelectronic devices, precisely controlling temperature gradients to reduce thermal stress.
4. Compatibility with Special Processes
   Rapid Thermal Processing (RTP): The sliding 70mm diameter tube furnace uses slide rails to quickly move samples in and out of the high-temperature zone, with cooling rates reaching 10°C/s (under vacuum/inert atmosphere), making it suitable for applications requiring precise control of phase transitions.
5. Multi-Atmosphere Switching Experiments: Supports vacuum-atmosphere cycling, simulating material performance changes under complex environments.

Selection and Usage Notes

1. Key Parameter Matching

Temperature Zone Length: The constant temperature zone length should be selected based on sample size (e.g., 300-400mm is common for a 70mm diameter furnace) to ensure uniform heating of the sample.

Automation Level: Manual loading and unloading is recommended for laboratory use. For industrial use, automated loading and unloading systems (such as a rotary tube furnace with a cooling fan) are recommended for improved efficiency.
