摘要

SiAlON 陶瓷是一种应用广泛的独特材料。利用现有的工业废料通过燃烧制备多孔 SiAlON 材料是非常有意义的。在这项工作中，通过在氮气中燃烧硅铁铝粉和硅酸铝空心微球的混合物，合成了一种多孔的 SiAlON 复合材料。硅酸铝空心微球用作孔隙形成剂。在硅酸铝铁粉中加入硅酸铝空心微球后，最终产品的总孔隙率从 34.1% 增加到 90.3%，开放孔隙率从 16.4% 增加到 88.2%，最大孔径从 53 μm 增加到 413 μm。合成样品的孔隙率主要是开放的。

Combustion synthesis of porous β-SiAlON from aluminum ferrosilicon and aluminosilicate hollow microspheres

SiAlON ceramics is a unique material used in various applications. Producing porous SiAlON material from available industrial waste by combustion is of great interest. In this work, a porous SiAlON composite was synthesized by the combustion of a mixture of aluminum ferrosilicon powder and aluminosilicate hollow microspheres in nitrogen. Aluminosilicate hollow microspheres were used as a pore-forming agent. The addition of aluminosilicate hollow microspheres to aluminum ferrosilicon powder increased the total porosity from 34.1 to 90.3%, the open porosity from 16.4 to 88.2%, and the maximum pore size from 53 to 413 μm in the final product. The porosity of the synthesized samples was predominantly open.
