BN is a material with the non-wet feature. So molten metal won’t be stuck onto the nozzle. Additionally, Boron Nitride ceramic is a kind of refractory ceramic with low expansion and high thermal conductivity. These features make it to be an ideal choice for atomizing nozzles. It’s very easy to be machined to custom design with precision and tight tolerance because of its machinability.
Boron nitride can be long-term used at 1800 degrees under a vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100 °C. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperatures.
