A process is being developed to produce high-purity titanium. As part of the proposed process, titanium will be kept in a quartz (silicon dioxide) crucible at 1273 K. A chemical engineer working on the process is concerned that the titanium could reduce the silicon dioxide, producing titanium dioxide and elemental silicon, which would lower the purity of the titanium. Is this concern justified? 

Data: At 1273 K
