New Application Area for Nitride Based Ceramics as Optical Materials

Abstract

This study is focused on the production of translucent nitride based ceramics changing different parameters such as additive, starting powder size and sintering conditions. Therefore, two different processes were followed in this research. In first one translucent SiAlON ceramics were improved by controlling specific parameters which were mentioned above. In the second stage, translucent Si<inf>3</inf>N<inf>4</inf> ceramic was obtained also the controlling same parameters. This is a very important result for aerospace and defence industry applications due to these materials high temperature resistivity and mechanical properties. © Published under licence by IOP Publishing Ltd.
