Our high temperature coatings
based on advanced ceramic materials (boron nitride, zirconium oxide,
yttrium
oxide) essentially find application when casting non-ferrous metals.
Due
to its excellent high temperature characteristics (non-wetting and
lubrication properties) and chemical stability these products are
superior to
conventional
products, for example on the basis of graphite and talc.

| Boron Nitride Coatings are used when casting aluminium, magnesium, zinc and lead. They contain "white graphite", produce non-wetting and lubricating surfaces and prevent efficiently adhering or sticking of melts. Due to their very good separation efficiency boron nitride coatings are used for coating moulds and dies in gravity and low pressure die casting as well as for casting of ingots, e. g. as used in the magnesium remelting plants of Rauch Fertigungstechnik, Austria. Automatic ladles are coated with boron nitride coatings in the area of pressure die casting. Further they find application with the continuous casting, for example with Wagstaff™ Casting Systems. |

| Graphite Coatings are used as a high temperature release agent for ferrous and non-ferrous metals, if good release characteristics are required and good adhesion to metal mould is demanded. Graphite shows high thermal conductivity. Due to the high oxidation capability graphite coatings should be used under protective atmosphere or inert gas only. |

| Zirconium Oxide Coatings apply with ferrous and non-ferrous melts, in particular when pouring very pure melts. They are usable up to 1900°C and are available with stabilized and non-stabilized (monocline) zirconium oxide. Zirconium oxide coatings are suitable for coating ceramics, fiber ceramics, graphite and metals.. |

| Yttrium Oxide Coatings show an extremly good thermodynamic stability against many highly reactive melts, for example titanium in investment casting and therefore can be used for casting high purity metals and alloys. They are suitable for the coating of fiber ceramics, graphite and metals and are applicable to 2200°C. |
