The process of converting hydrated alumina
Webb10 apr. 2024 · Hydrated salt phase change materials (PCMs) can play an important role in the temperature regulation of buildings by storing and releasing latent heat. However, hydrated salt PCMs are affected by phase separation, supercooling, and leakage, which greatly limit their application. In this study, an innovative modified calcium chloride … WebbA process is described for the direct chlorination of hydrated alumina (preferably alumina trihydrate) to aluminum chloride hexahydrate (ACH) by reaction with concentrated hydrochloric acid. Preferably all of the initial hydrated alumina is converted to ACH. The ACH partially calcined to form an amorphous mixture of aluminum oxides and …
