Boron Nitride Nozzle

Hot press boron nitride nozzle is made using a hot pressing process from densification of powder to a lubricious white solid. It exhibits a hexagonal structure and a unique combination of chemical, electrical,mechanical and thermal properties, making it suitable for a wide range of high performance industrial applications.
Reasons for using bn nozzles:
easy to machine
non wet by most molten metals
will not clog or plug holes
applications:
continuous casting
heat treatment fixtures
refractory applications
high temperature valves
high temperature lubricant
motel metals and glass casting
nozzles for transfer or atomization
crucibles and containers for high purity molten metals
high-temperature & high-voltage electrical insulators
vacuum furnace supports which require electrical resistivity
finished items with fine intricate detail, threads and small holes
retains strength through temperature range up to 2000°c
replaces alumina and zirconia nozzles prone to thermal shock.
