【Abstract】 This paper summarizes the technology of making Si₃N₄-SiC refractory materials in reaction sintering,the growth mechanism of Si3N4,and the nitride reaction dynamics of Si.It analyses the possibility to simulate the temperature field during firebricks processing.In order to improve the firebricks quality and optimize the operating parameters,it puts forward that the firebrick reaction process can be controlled strictly by the temperature field simulation.更多还原
