Abstract: The invention provides a method for producing titanium tetrachloride by using a low grade titanium material, and belongs to the chemical field. The technical problem to be solved is to provide a method for producing titanium tetrachloride by using a low grade titanium material capable of continuous industrialized production. The method is characterized in that the low grade titanium material containing a certain proportion of titanium carbide is caused to directly react with chlorine at 600-700° to produce the titanium tetrachloride. Long-time continuous and stable operation can be realized by using the process parameters of the method, and chlorination rate of the titanium carbide in the titanium material reaches above 90%, so that the titanium material can be better used for producing the titanium tetrachloride.
