TP series
RF Induction Thermal Plasma
Generates thermal plasma at about 10000 degrees by high-frequency induction through a physical / chemical reaction process, enabling nanoparticle synthesis and thick film synthesis (film formation)
Features
Principles・Features
The radio-frequency thermal plasma operates at atmospheric pressure, or in a low-pressure environment close to atmospheric pressure, concentrating the high-frequency power at a specific location to spontaneously generate an approximately 10,000 degree plasma from various gases using Electromagnetic induction.
This thermal plasma is an area of the arc discharge. By introducing materials (powders, gas, fluids) into the plasma it is possible to induce vaporization, melting, dissociation, and chemical reactions for applications such as nano-particle synthesis, powder spherodization and reaction, film formation, and dissociation of harmful gases.
Compared to the direct current (DC) arc discharge, a larger plasma volume can be obtained
The gas flow is also better than that of the DC plasma. Since the flow rate is an order of magnitude slower, it is possible to adequately heat the materials to induce the desired reactions.
Since there are no electrodes, there is no contamination from electrode materials, enabling high-purity processing.
A wide range of gases can be used, including oxidative, reductive and corrosive gases
Fine particles can be created, with a fineness on the nano-order, a level beyond the capability of mechanical pulverization
Being able to make use of the reactions of high-energy chemical species, such as atoms, ions, excited molecules and radicals, opens the possibility to create new substances and materials.

Product line-up（Nominal output）：6kW ，35kW ，100kW ，200kW
*A 300kW type has also been produced
Plasma torch
There is dedicated plasma matching for each of the high-frequency oscillation mechanisms.
High-density plasma torch diameter and formation
Two-layer cooling water piping is used, with an inner pipe made from a ceramic that is more durable than the quartz pipes ※ (patented). This enables stable operation over a long period of time, from low pressures to atmospheric pressure.
Exceptional durability in comparison to the quartz pipes
We have also been developing a hybrid plasma torch that combines both direct current (DC) and radio-frequency (RF) methods. The features of the hybrid method include;
A radio-frequency plasma assist effect by overlapping the direct current plasma jet directly on top of the radio-frequency plasma
For nano-particle synthesis, it is possible to pre-heat the raw materials using the DC plasma, enabling more efficient vaporization (smaller particles).
System
We offer systems to suit applications including nano-particle formation, film deposition, and research applications
The hot plasma generator (component) is also available.
