Summary
[edit]DescriptionAluminumFromClay 001.jpg | The final step in the production of alumina from clay in the pilot plant at the National Bureau of Standards is the conversion of hydrated aluminum chloride to alumina by calcination. The aluminum chloride crystals are fed into the hopper at the top of the 20-foot Herreshoff furnace and are stirred constantly by rabble arms as they pass downward over the heated hearths. | ||||
