##### Abstract [en]

Thermal conductivity measurements show that ice continues to amorphize for several days when kept at a fixed pressure p in the 0.79–0.88 GPa range, and fixed temperature T in the 127–130 K range. Thermal conductivity k decreases according to a stretched exponential in time, and its limiting long time value k($\infty$) varies with p and T. At 0.8 GPa and 128 K, k($\infty$) remains 2.5 times the value observed for high-density amorph. Consequences of these findings for our understanding of amorphization are discussed.
