Boron Nitride Crucibles For High-Temperature Furnace

Boron Nitride Crucibles For High-Temperature Furnace

A typical design of high-temperature furnaces operating at temperatures significantly higher than 1600°C incorporates heating elements manufactured from graphite, tungsten, or molybdenum disilicide. There is a need to electrically insulate these heating elements from the furnace environment using high-temperature ceramics.

While oxide ceramic insulators are commonly used in low-temperature furnaces, they are not as well suited for high-temperature furnaces. They become highly stressed at high temperatures, especially under shorter production cycles with faster heating and cooling rates. This leads to premature component failures and increased furnace downtime.

For thermal processes at extremely high temperatures and vacuum or in inert conditions, Boron Nitride insulators and components present the only viable solution. INNOVACERA BN is the material of choice in these applications due to its high purity, and therefore operating temperature up to 2000°C in an inert atmosphere.
