Ceramic Si₃N₄ samples with Мо and AI admixtures have been investigated by spectroellipsometry. The influence of admixtures on the ceramics optical properties have been studied. The local defects of Si₃N₄ crystal structure are responsible for the band gap reduction. The silicone oxynitride amount in...
