详细
The thermal expansion of magnesium borate (Mg3B2O6) is studied by the method of X-ray thermodiffraction in the temperature range 25–1100°C. The coefficients of thermal expansion are calculated as follows: αa = 13.0(5), αb = 8.5(5), αc = 8.0(5), αV = 30(1) × 10–6°С−1 at 25°C; and αa = 20.0(5), αb = 13.0(5), αc = 13.0(5), αV = 46(1) × 10–6°С−1 at 1100°С. The direction of the maximal thermal expansion (αa) is perpendicular to the preferred orientation of the BO3 triangles.
