From the correlation between the Si-O-Al angle and the Si-Al distance in the c-axis direction, the expansion of a-axis and the contract of c-axis brings the split of Si-O-Al angle distribution. At the same time, the stable position of Li+ ion sites also changed. This suggests the cation position also important in the mechanism of low-thermal expansion observed in silicate materials.}, pages = {146--148}, title = {β-LiAlSiO4結晶の温度変化シミュレーション}, volume = {19}, year = {2020}, yomi = {サワグチ, ナオヤ} }
