1. Boron Nitride
Boron Nitride products are manufactured as powders, finished components and blanks, as well as liquid coatings for various high temperature applications in molten metal equipment. Boron Nitride is an advanced ceramic material available in powder, solid, liquid and aerosol spray forms and in solid state it can be machine very easily using diamond tooling.
Boron Nitride can easily be machined to close tolerances in virtually with any complex shape. After machining, it is ready to use without additional heat treating or firing operations. In inert and reducing atmospheres, Boron Nitride will withstand temperatures over 2, 000° C. It is not wet by most non-ferrous molten metals and slags and can therefore be used as a container for most molten metals including aluminium, sodium, iron, steel, silicon, tin, copper, magnesium etc. Metals.
