| Abstract: | The lattice parameters of arsenic have been determined at various temperatures between 28 and 286° C, using 19 cm diameter, high temperature camera. The a-parameter is observed to increase between 28 and 200° C and thereafter it decreases up to 286° C. The c-parameter is found to increase parabolically throughout the range of temperature. The mean values of thermal expansion coefficients along, and perpendicular to, the principal axis between 28 and 200° C are 44.3×10−6/° C and 3.1×10−6/° C respectively. |
