摘要
By analyzing the relationship between thermal expansion coefficients of AB type halides and their crystal chemistry properties, an empirical formula for theoretical calculation of their thermal expansion coefficients is drawn. The formula has a simple form and a high accuracy with an average error of 2 4%.
