On the other hand, the chloride process involves heating the ore with chlorine gas to produce titanium tetrachloride. This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxidetitanium dioxide is prepared from factory. The chloride process generally results in a higher purity product and is more energy-efficient, but it requires sophisticated equipment and handling due to the corrosive nature of chlorine gas.
