The retarded sublimation of red phosphorus
Abstract
Vaporization coefficients for red phosphorus (form IV) were determined to the range 620–690 K at phosphorus saturation ratios (p*/p°) of 0.08–0.29 and in the presence of nitrogen at ca. 1 atm. At 650 K, αv(p*/p°= 0.18)= 2.5 × 10–8. The effect of iodine on the sublimation rate was examined.
