Abstract The phase field method was used to simulate the growth of pure α-Al₂O₃ grain generated in situ during high temperature sintering process of alumina fiber prepared by the sol-gel method. Combined with experiments, study the growth behavior and dynamics of α-Al₂O₃ grains at different sintering temperatures and different initial Al₂O₃grain size in the high temperature sintering stage was studied. Both phase field simulation and experimental results show that in the sintering temperature range of 1200-1 500 ℃, the grain growth rate increases significantly with the increase of the sintering temperature, and the grain growth rate is the fastest in the temperature range of 1 400-1 500 ℃. The smaller the initial grain size, the greater the grain growth rate. The simulation result shows that the increasing unevenness of grain size can also promote grain growth.
