Boron Nitride Rod Descriptions
Precision-engineered from high-purity hexagonal boron nitride (h-BN), our Boron Nitride Rods deliver a unique combination of high thermal conductivity, excellent electrical insulation, and outstanding thermal shock resistance. They maintain structural integrity up to 850°C in air and significantly higher in inert or vacuum environments. Chemically inert and non-wetting to most molten metals, slags, and glasses, these rods resist corrosion and prevent contamination in demanding industrial processes. Easy to machine into custom diameters, lengths, and threaded configurations, Boron Nitride Rods are ideal for thermocouple protection sheaths, high-temperature furnace supports, semiconductor manufacturing components, plasma etching parts, and molten metal handling systems.
Boron Nitride Rod Advantages
