About Aluminium Nitride:
Aluminum Nitride (https://en.wikipedia.org/wiki/Aluminium_nitride) or AlN is known as nitride of aluminium, is a grey colored semiconductor material. It was discovered more than a century ago in 1877, but it was not until the middle of the 1980s, its viable engineering properties were discovered. It has high coefficient of thermal expansion and thermal conductivity. Its coefficient of thermal expansion strongly matches Silicon wafer material, resulting to its attractive electronics applications. Its high thermal conductivity makes it an electrically insulating ceramic material.
Machining & Grinding of Aluminum Nitride
Aluminum Nitride can be machined into fully dense states in the form of green biscuits. In Green biscuit form it can be machined easily into any complex geometry. However, the sintering process followed during Machining Aluminium Nitride (http://top-seiko.com/material-cat/machining-aluminum-nitride-products/) can fully densify the material. It causes the AlN body to shrink 20% of its actual size. This shrinkage makes it difficult to hold very tight tolerances for pre-sintering aluminum nitride.
So to achieve very tight tolerances, fully sintered AlN is grounded with diamond cutting tools. In this process a very precise diamond coated tools are used. These tools abrade the material until the desired form is created.
