I'm looking for a type or model of capacitor that heats up. We want to attach some capacitors to the walls of an ablation chamber so that we can run an electrical current through them and heat the chamber walls through conduction, so that the superheated gas inside the chamber does not deposit on the chamber walls. This means I'm looking for a capacitor that heats up to the temperature of a superheated material. Someone recommended I look into thermal capacitors but I can't find much about them. Any capacitors suggestions or knowledge about thermal capacitors?
