Preparation of beta-SiAlON by combustion synthesis and characterization

Abstract

beta-Si_6-zAl_zO_zN_8-z powders were prepared via a self-propagating combustion of powder mixtures composed of Si, SiO₂, Si₃N₄, AlN, and Al₂O₃ under 6 MPa N₂. Effects of processing parameters such as z values and starting compositions on the combustion temperatures and properties of synthesized powders were systematically investigated in order to obtain fundamental data for future investigation on combustion synthesis of SiAlON phosphors.
