Abstract
The thermal expansivity α p is related to isothermal compressibility κ T at various pressures for constant temperatures of 254.6, 274 and 297.5 K close to the melting pressure in ammonia solid III. By analyzing the experimental data for κ T according to a power-law formula, a linear variation of α p with the κ T is established here close to the solid-liquid transition in ammonia. Anomalous behavior of thermal expansivity α p and the isothermal compressibility κ T near the melting pressure is indicative of the λ-type transition in ammonia solid III.
