Insulmicanite® products are placed between the coil and the refractories in induction furnaces :

- They protect the coil from mechanical stresses resulting from the expansion and movement of the crucible
- They improve electrical insulation during sintering
- They can be used to adjust the sintering depth and to reduce heat losses from the furnace
- They reduce the risk of perforation when the crucible wears or cracks
- They can be used in the electronic detection of defects in the crucible
- They facilitate the removal of a worn crucible
