Product Overview

Description



Material Introduction


Hexagonal Boron Nitride Ceramics
At UNIPRETEC, we produce several advanced ceramic parts with fine engineered ceramics, and one of those is Hexagonal Boron Nitride. We generally choose a form known as hexagonal boron nitride (h-BN). Hexagonal BN is a composite of boron and nitrogen that is both heat and chemically resistant. It is the most robust crystalline type of boron nitride, along with graphite. Since it has a composition identical to graphite, although you will even hear it named "white graphite" since it is white in colour. What is more, hardness of hexagonal BN is similar to graphite, so it is very easily to machine the parts into required shape, only one small tip, machining work should be process in dry conditions with no cooling liquid. Also, visible dust can be created during machining, so wearing mask and goggle is necessary.
