Breakthrough in Scaling Up SWCNTs Production | Specialized Plasma Arc Synthesis Equipment Empowers I
The release date：2026-05-26 Source：原创 viewed：29Allow users to customize material properties.Plasma Arc synthesis, leveraging an ultra-high-temperature reaction environment, a high-purity inert atmosphere, and an efficient catalytic growth mechanism, has become the preferred process for producing highly crystalline, high-purity SWCNTs, and is also the core technological direction for the current industrial-scale implementation of SWCNTs.
We focus on Plasma Arc Method SWCNTs specialized equipment R&D, manufacturing, and turnkey line solution delivery. With precise process control, stable system design, and industrial-scale production standards, we solve the pain points in single-walled carbon nanotube preparation, helping research institutes and advanced materials enterprises streamline the entire workflow from experimental R&D to pilot testing and mass production.
Plasma Arc Method: The Core Preferred Choice for High-Quality SWCNTs PreparationI. Technical Principles
In a vacuum/low-pressure inert atmosphere (He/Ar), a DC high voltage and high current is applied between the graphite anode and cathode, breaking down the gas to form an arc plasma. The arc instantaneously sublimates the graphite into carbon vapor, while the catalyst simultaneously generates nanoscale metal clusters.
Relying on temperature gradients and atmosphere convection, carbon vapor undergoes dissolution, precipitation, and self-assembly on the surface of catalyst particles, enabling the orderly growth of high-quality single-walled carbon nanotubes.
The core temperature of the arc can reach 3000–5000°C, allowing the vaporization of the carbon source, catalytic nucleation, and tube growth to be completed simultaneously, resulting in finished products with fewer defects, high crystallinity, and excellent purity.
