Boron nitride is used wherever maximum precision is required under extreme conditions. Typical examples include high-temperature furnace construction, where HeBoSint® materials are used as electrical insulation sleeves for heaters. In solar technology (photovoltaics), electrically insulating boron nitride ceramics protect the sensitive graphite or copper heating elements in the production of silicon wafers. Even in space, for example in plasma drives for satellites, the electrical insulation provided by boron nitride prevents short circuits and ensures a constant electrical field. It is also the proven material in PVD systems, where it ideally combines insulation, temperature resistance and non-stick properties.
