Thermal expansion of beta-rhombohedral boron

• The cell dimensions of beta-rhombohedral boron have been measured in the temperature range 10-1273 K, using X-ray diffraction. The linear thermal expansion coefficients (alpha(l)=(l-l(298))/l(298) (T-T-298)) were determined along the a and c directions.
