Hip sintering
Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The process can be used to produce waste form classes. Calcined radioactive waste (waste with additives) is packed into a thin walled metal canister. The a… Webb3 sep. 2024 · HIP処理条件は、温度1350℃、HIP圧力150MPa、保持時間1時間とした。 なお、圧力媒体には純度99．9％のアルゴンガスを用い、試料はアルミナ製の密閉容器を用いて処理した。
