Induction Heating Silicon Carbide

To generate plasma, we apply an electrical field to a gas, with the goal of removing electrons from their nuclei. These free-flowing electrons give the plasma key properties, including its electrical conductivity, a magnetic field, and sensitivity to external electromagnetic fields.

In this application test, the customer provided sample parts to be induction heated. Ultraflex demonstrated the ability of the UPT-SB High Frequency Induction system to heat the silicon carbide cylinder to 2700-2800°F (1480-1540°C) within three minutes. This demonstrated the feasibility of the system for induction heating silicon carbide for plasma research.
