Development, characterization and oxidation behaviour of Si3N4Al2O3 ceramics

Synthesis, phase transformation and mechanical property of SiAlON ceramics from coal gangue

“…The reaction of carbon involved tended to produce gas product and thus caused β-SiAlON ceramics synthesized to possess lower density and MOR. In addition, the mechanical property of SiAlON ceramics is not as good as that reported in the literature [21][22][23][24]. This was probably caused by the processing method [23,24].…”

“…In addition, the mechanical property of SiAlON ceramics is not as good as that reported in the literature [21][22][23][24]. This was probably caused by the processing method [23,24]. Advanced processing technique such as hot isostatic pressing (HIP) can be applied to obtain higher MOR.…”

“…Most work is focused on investigating the mechanical property of monolithic SiAlON ceramics prepared from pure oxides and nitrides [23][24][25]. Studies concerning the mechanical properties of SiAlON ceramics prepared from natural materials are scarce.…”

“…which may be of cost effectiveness [11][12][13][14][15][16][17]. However, due to the complicate compositions of natural aluminosilicate minerals, the experimental condition to synthesis SiAlON is difficult to control [1,[17][18][19][20]. How to optimize the experiment parameters for SiAlON synthesis will be of great importance and has been aroused the interest of the researchers.…”
