After the death of diatoms, their sturdy and porous shells-cell walls will not decompose, but will sink to the bottom of the water and become diatomaceous earth after hundreds of millions of years of accumulation and geological changes. Diatomite can be mined and has a wide range of industrial uses. It can be used to manufacture industrial filters, heat and sound insulation materials, etc. The founder of the Nobel Prize, Alfred Nobel, discovered that the unstable silica produced by diatoms can be stably made portable. It is also speculated that oil comes from the oil produced by ancient diatoms. It is also believed that 3/4 of the organic matter on the earth comes from photosynthesis of diatoms and algae.

Diatoms have been widely used in various fields
Under the microscope, diatom mineral is a nano-scale porous material with a porosity of up to 90%, and it is regularly and neatly arranged into circles and needles. Because of its high porosity, it has many special technical and physical properties, such as large porosity, strong adsorption, light weight, sound insulation, wear resistance, heat resistance and certain strength. The dissolution of diatoms constitutes a diatom mineral—diatomite.
