Abstract
The one atmosphere isobaric phase relations have been determined for the system As-Sb, using a simple experimental arrangement where a low melting temperature alkali halide melt acts as a reaction vessel. The one atmosphere univariant temperature, where a liquid of composition 45.5 mol % As, plus a solid of composition 62 mol % As and a gas of composition 89 mol % As coexist, is 666° ± 3° C. The one atmosphere sublimation point of As was measured as 611° ±2° C. Arsenic and antimony are hexagonal isostructural compounds with a complete solid solution series between them. The a cell edge and volume of the unit cell vary linearly with composition in mol percent. The c edge changes in a markedly nonlinear manner with composition. The measured unit-cell parameters at 25° C are: As, a = 3.760 ± 0.001 A, c = 10.555 ± 0.003A, V = 129.2A3; Sb, a = 4.310 ± 0.001 A, c - 11.279 ± 0.003A, V = 181.4A3.
