Abstract: The carbothermal reduction nitridation of alumina powder contAlNing MgAl2O4 spinel was investigated. Its results show that a great dcal of aluminum oxynitride spinel could be manufacturedat the temperatures lower than 1600℃ and the content of aluminum oxynitride phase and its compositions in the product strongly depend on the firing temperatures and adding MgAl2O4 spinel.Aluminum oxynitrides resulted from different adding content of MgAl2O4 at varied temperaturespossess different lattice parameters.

Key words: carbothermal reduction, MgAl2O4 spinel, powder, synthesis
