Let’s discuss a very tricky container problem!

We use a three-phase arc furnace, in which three electrodes are used to break down the material inside the furnace through arcs. The temperature inside the furnace reaches 1600 degrees Celsius. The problem is that the electrode tips used to hold the electrodes are often damaged by the arcs. I’m wondering if there are any insulating materials that can withstand high temperatures, such as those capable of withstanding around 1000 degrees Celsius.
High-temperature resistant ceramics, or refractory bricks reinforced with refractory cement, can be considered.
