In this article, the global diatomite reserves and production in recent two years are summarized, and the distribution of diatomite in China is described. It is pointed out that diatomite is rich and relatively concentrated in China, which is an important non-metallic mineral resource and is easy to be developed on a large scale. Also, the relationship between the surface hydroxyl structure and the pore structure of diatomite and its application is analyzed. Also, its application in traditional industries and strategic emerging industries is reviewed. It is suggested that high quality diatomite is a scarce resource and the development of medium and low-grade diatomite should be strengthened in the future. At the same time, considering the physical and chemical characteristics of diatomite, the research on micro-modification of its surface and the artificial control of micro-porous structure should be strengthened to expand its application in strategic emerging industries. This paper has an important reference value for the application research of diatomite in emerging industries.
