A Comparative Study of SiAlON Ceramics

Mallik, Awadesh Kumar; Açıkbaş, Nurcan Çalış; Kara, Ferhat; Mandal, Hasan; Basu, Debabrata (Elsevier, 2012)

Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% b-Si3N4 was used from refractory grade powders (B1) and another purer 98% a-Si3N4 (50A) powder was used to prepare the SiAlON samples. ...
Effect of sintering conditions and heat treatment on the properties, microstructure and machining performance of α-β-SiAlON ceramics

Açıkbaş, Nurcan Çalış; Yurdakul, Hilmi; Mandal, Hasan; Kara, Ferhat; Turan, Servet; Kara, Alpagut; Bitterlich, Bernd (Elsevier, 2012)

The properties of SiAlON ceramics are strongly affected by the composition and structure of the intergranular phase, which are controlled by dopants, sintering conditions and starting silicon nitride (Si3N4) powder ...
Influence of Beta-Si3N4 Particle Size and Heat Treatment on Microstructural Evolution of Alpha:Beta-SiAlON Ceramics

Açıkbaş, Nurcan Çalış; Kumar, Rudra; Kara, Ferhat; Mandal, Hasan; Basu, Bikramjit (Elsevier, 2011)

In the present study, we report the effects of starting beta-Si3N4 particle sizes and post-sintering heat treatment on microstructure evolution and mechanical properties of prepared alpha-beta SiAlON ceramics. Three different ...
