Hot Pressed Hexagonal Boron Nitride (HPBN/HBN) is an ideal material, which is used to make the Nozzles for molten metal atomization. It is lubricious, machinable, chemical inert, thermal shock resistant and non-wet by molten metal.

Specifications or shapes of BN Ceramic Spray Nozzles are very flexible, because customized sizes can be easily achieved by normal tool machining work from hot pressed BN Boron Nitride blocks. Here we can see that BN is a lubricious, soft and machinable material, besides, Boron Nitride is with the platy hexagonal structure, so it's often referred to as "white graphite". Both BN and graphite are thermal shock resistant and widely used in high temperature environment, however, BN is a very good electrical insulator. Furthermore, in order to get different properties, Boron Nitride can be composited with other materials, like Aluminum Oxide, Aluminum Nitride, Silicon Carbide, Zirconium Oxide... According to different customers' applications, UNIPRETEC is good at producing solid Boron Nitride in different grades.
