Metallurgical Industry An Overview Sciencedirect Topics

Aldo Steinfeld, Anton Meier, in Encyclopedia of Energy, 2004. 3.2.1 Solar Metals, Metallic Oxides, Carbides, and Nitrides. The extractive metallurgical industry is a major consumer of process heat and electricity and is responsible for approximately 10 of global anthropogenic greenhouse gas emissions. A solar thermal process would drastically reduce these emissions.

Hydrolysis Of Ball Milling Albihydride And Albisalt

ball milling was performed by QM-1SP planetary ball miller under 0.20.3MPa argon atmosphere. Ball-to-powder mass ratio corresponds to 301. The hydrol-ysis reaction of the mixture 0.1g with pure water was carried out in a stainless steel chamber attached to a gas burette graduated in 0.1ml increments at room temperature.
