What are Sialon Ceramics?

What are Sialon Ceramics? SiAlONs are ceramic alloys based on the elements silicon (Si), aluminium (Al), oxygen (O) and nitrogen (N) and were developed in the 1970s to solve the problem of silicon nitride (Si 3 N 4) being difficult to fabricate. As alloys of Si 3 N 4, SiAlONs exist in three basic forms.

Introduction to SiAlON Ceramics

2018/4/3SiAlON ceramics are innovative refractory materials based on the chemical composition of silicon nitride (Si 3 N 4). They can compete with the strongest and most durable refractory materials currently available, due to their unique mechanical and thermal properties, with wide-reaching applications in metallurgical, petrochemical, and other high-temperature industries.

Preparation, structure and mechanical properties of

2020/3/20Abstract Sialon ceramics were prepared by the nitridation of Si, Al and Al2O3 powders with the transition metals (Fe, Co, Ni) catalysts. The phase composition, microstructure and mechanical properties of specimens were studied. Compared with the catalyst-free specimen, the addition of Fe, Co and Ni greatly promoted the nitridation process of Sialon ceramics and improved the weight gain rate
