Reaction of titanium and mno2

http://web.mit.edu/2.813/www/readings/Ellingham_diagrams.pdf WebThe most important oxide of titanium is the titanium dioxide (TiO2 ), which crystallizes in three structural forms. They include brookite, anatase, and rutile. Rutile is the thermodynamically preferred form at all temperatures. The ores are converted to pigmentary TiO 2 by one of two main routes.
