This material offers a hitherto unattainable combination of outstanding properties:
The sintering process of silicon nitride has to take place by a very high mechanical pressure in a controlled atmosphere. Depending on the process the result is:
RIn comparison reaction bonded nitride (RBSN) - starting substance Si-powder - is nitrided shrink free in a specifically set N2-atmosphere.
It is mainly based on compounds or solid solutions of a four-component system silicon - aluminium - oxygen - nitrogen. On account of its fracture toughness it is often used for
An irresistible material due to its extraordinary high thermal conductivity: up to 180 Wm-1 K-1. Moreover the combination of properties speak for themselves:
ALN is especially suitable as
