Advantages of an inductive plasma, as used at SI:
- No contamination from the heat source. (no OH-contamination, no metal parts in the heated zone of the flame.
- Free choice of gas. ( Argon, Nitrogen, Air, i.e. compressed air)
- High flame temperatures. (Argon (A) around 15.000 K and Nitrogen (N) around 8.000 K)
- Plasma power and process parameters are completely computer controlled.
