Within this range. titanium dioxide TiO2 carrier mobility depends on the phase and amount of impurities in the material. Anatase and plagioclase phases tend to have higher mobility than rutile phases. but both are significantly lower than many other common semiconductor materials. Material defects. dopants and temperature can also affect mobility.

Q how is titanium produced

Titanium is manufactured through the Kroll process. which involves multiple steps. First. titanium ore is extracted from the earth. Then. it is refined to produce titanium dioxide. using mainly rutile and titanium ore. Next. the titanium dioxide is converted to titanium chloride by heating it with carbon and chlorine at around 1000C. This results in the production of a volatile liquid called titanium tetrachloride. In the Kroll process. this compound is reduced using magnesium in a containment vessel known as a bomb. The reduction occurs at temperatures of 800-850C and causes a reaction between magnesium chloride and titanium sponge. The resulting product then undergoes purification by vacuum heating to remove excess magnesium or magnesium chloride. Following this. the purified sponge is melted into ingots under a vacuum or inert gas atmosphere. These ingots are then machined into various shapes for different applications such as sheets. tubes. rods. and wires. Despite its complexity a...
