Abstract Titanium dioxide commonly known as titanium white is the third largest inorganic chemical product
after synthetic ammonia and phosphorus chemical industry. China is the world's largest producer and consumer of
titanium dioxide. The sulfuric acid process, chlorination process and hydrochloric acid process of the titanium diox‐
ide production are reviewed, and the advantages and disadvantages of each process are analyzed in detail. China
is vigorously developing the clean production process of titanium dioxide. We should strive to improve the technol‐
ogy level of the sulfuric acid process, and eliminate the backward production facilities. At the same time, adjust‐
ment and layout of the chlorination process should been emphasized. The development of new processes and tech‐
nologies for the production of high-quality titanium dioxide are also important to realize the sustainable develop‐
ment of titanium dioxide industry in China.
