Vacuum Evaporation of Salt from Titanium Sponge.
Met Trans 1974 Jan; 5:53-58
The rate of salt removal from titanium sponge was determined using a thermogravimetric technique. Both magnesium- and sodium-reduced titanium sponge were used in the investigation. Measurements were made of the rate of salt removal by vacuum evaporation for a range of temperature, bulk density, and sponge surface areas. Removal of magnesium chloride was characterized by the presence of a long period of surface evaporation, or constant-rate drying, during which the major portion of the salt was evaporated. Sodium-reduced sponge showed no such constant-rate period.
