At present, with the rapid development of science and technology, the research on limonite rotary kiln refractory has been gradually put on the agenda, and some good results have been achieved, such as the carbon nanotube composite refractory technology to be described at present.

Carbon nanotubes have good properties, so they are introduced into refractories as a new material, and then limonite rotary kiln refractories with high performance are developed. However, the following problems may be involved in its use: carbon nanotubes will change into other substances or be oxidized at high temperature; It is easy to agglomerate, which is not conducive to dispersion. Limonite rotary kiln experts have made research on these problems.

The first is to change the relationship between its structure and admixture, select the appropriate silicon source and temperature, and prevent the material from qualitative change. Then, a coating is formed on its surface, which can not only prevent its alteration, but also improve its overall performance. Finally, the catalyst is used to form carbon nanotubes at high temperature, which improves the performance of limonite rotary kiln materials.
