Aluminum Oxynitride (AlON)-Powder
Product Description
Characteristic
Aluminum Oxynitride is a transparent optical ceramic powder with grain size of D50~20μm. Aluminum oxynitride has a cubic spinel crystal structure and is four times harder than silica glass and three times harder than steel' .One of the materials with high potential for application as a refractory material is aluminum oxynitride with spinel-type structure, γ-AlON. AlON materials, single-phase or composites, are characterized by good mechanical properties, high thermal shock resistance and a high corrosion and erosion resistance. Another advantage is possibility of usage of SHS method for producing of relatively good sinterable powders of γ-AlON, however, are characterized by poor compressibility.
