MELTING OF SILVER HALIDES AT HIGH PRESSURE

The melting curves of silver chloride, bromide, and iodide are determined up to 68 kbar. The present silver chloride and bromide melting curves are higher by 5°-20°C than those of Deaton. The triple point of silver iodide (I)-silver iodide (III) is at 19.1±0.5 kbar and 678°±1°C whereas Deaton reported the triple point at 22 kbar and 680°C. The volume compression versus the melting-temperature plots are linear at low compression and begin to curve towards ΔV/V0 axis at higher pressures. © 1969 The American Institute of Physics.
