Common chemical properties The alkali metals are so chemically reactive that they are never found free in nature. Sodium and potassium react explosively with water to produce hydrogen gas. The alkaline earth metals are not quite as reactive as the alkali metals. The alkali metals react with water but not explosively. The transition metals are generally the least reactive of all the metals. However, when they combine with other elements, they form a large variety of colored compounds. Chromium oxide is green, titanium oxide and zinc oxide are white, manganese oxide is purple, and iron oxide is ochre.

In borosilicate glasses, the amber color is developed through interaction between iron oxide and titanium oxide or iron oxide and manganese oxide. Reducing agents are not used in borosilicate glasses for color development. Borosilicate ambers are called oxidized ambers. 

The desire to find more robust layered stmctures which will maintain their integrity under the extreme conditions found in FCC, or contain different catalytic activity for other types of important industrial reactions has led to the investigation of layered metal oxides. These include certain semiconducting niobium/titanium oxides and manganese oxides. 

The electrochemical processes for manufacturing manganese IV) oxide are currently the most important, industrially. Ca. 165 10 t of EMD was produced in 1986. A purified sulfuric acid manganese(II) sulfate solution is electrolyzed at 90 to 95°C on lead, titanium or graphite anodes at current densities of 0.5 to 1.2 A/dm-, whereupon mangane.se(II) is oxidized to manganese Ill) ... 

The anodes are periodically taken out of the electrolysis unit and the 1 to 3 cm thick layers of e-MnOi formed are mechanically removed, ground, washed and dried producing a product with 92% Mn02 and 3 to 5% of water. The titanium and graphite anodes can then be reused. In order to maintain the Mn II)-ion concentration in the electrolyte con.stant during the electrolysis, fresh electrolyte is added continuously or intermittently and the spent electrolyte taken off and used for manganese II) oxide dissolution. 

This aspect of emulsion flotation, however, has not been systematically studied. Emulsion flotation has been employed in the treatment of ores containing, iron, manganese, molybdenum and titanium oxide. (9-11) A major role of emulsion of fatty acids in the flotation of Florida phosphate rock also cannot be... 

Baldwin et al. (1995) surveyed the effect of various mineral phases on the rate of hydrolysis of the model organophosphate ester p-nitrophenyl phosphate. They found that, normalized for the number of independently determined phosphate adsorption sites, the manganese oxides were most effective in catalysing the hydrolysis reaction, followed by iron and titanium oxides, with a small effect for alumina. No effect was...
