In the production process of titanium dioxide, multiple high-temperature equipment and reactors are involved, and some refractory materials are required to withstand high temperatures and chemical corrosion. Here are some refractory materials that may be used:

Titanium dioxide calcination kiln: The calcination kiln is used to calcine the titanium dioxide precursor material at high temperatures to form the final product of titanium dioxide. Refractory materials are used in the lining, furnace wall, and combustion chamber of the kiln to resist high temperatures and chemical erosion.

Reactor: In the process of titanium dioxide production, some reactors may be involved, such as chlorination reactor and titanium sulfate reactor. These reactors usually require the use of refractory materials to construct parts such as lining, reaction chamber, and outlet to withstand the corrosion caused by high temperature and chemical reactions.

Filters and Dryers: In titanium dioxide production, filters and dryers may be required to handle and separate solid particles. The interior of these devices may require the use of refractory materials to withstand high temperatures and particulate attacks.

Conveying pipelines and storage equipment: During the production process of titanium dioxide, pipelines, and storage equipment are needed to transport and store raw materials and finished products. These piping and equipment may require the use of refractory materials to resist corrosion from high temperatures and chemicals.

It should be noted that the specific type and composition of refractory materials used will depend on the specific production process, process parameters, and material properties. In practical application, specific refractory materials should be selected according to the production process and equipment requirements.
