Synthesis and mechanical properties of Bi2O3-Al4Bi2O9 nanopowders

Abstract

As a result of great surface area and a great number of energetic sites, ceramic nanocomposites are being considered as good adsorbents and catalysts. Al₂O₃ nanoparticles are widely used in high-tech applications owing to their excellent properties. Besides, Bi-based oxides have been the center of attention for applications such as remediation of hazardous wastes and wastewater photochemical degradation of organic contaminants and remediation of hazardous wastes. In this research, the synthesis of Bi₂O₃-Al₄Bi₂O₉ nanocomposite and its mechanical properties as a novel composition were investigated. The results showed that the prepared Bi₂O₃-Al₄Bi₂O₉ sample exhibited the Al₄Bi₂O₉ crystalline peaks. Additionally, the prepared nanocomposite showed no impurities. The mechanical properties of the Bi₂O₃-Al₄Bi₂O₉ sample were improved in comparison with Al₂O_3, Bi₂O₃, and Bi₂O_3- Al₂O₃, which offer it as a promising alternative to Bi₂O₃-Al₂O₃ composite ceramic.
