• Sommario/riassunto: A Complete Guide to Magnesia-From Mining to End UseOften relegated to footnote status in texts, magnesia is nevertheless a valuable substance widely used in applications ranging from wastewater treatment to catalysis. The Chemistry and Technology of Magnesia fills the long-standing gap in the literature with a comprehensive, one-stop reference to ""all things magnesia.""The book brings together the many strands of information on magnesium compounds, their production, testing and evaluation, technology, applications, and markets. Opening with an introductory history of the chemi
