Diatomite is generally formed from the silicate remains of single-celled algae known as diatoms after they die, which are essentially hydrated amorphous SiO2. Diatoms can survive in both freshwater and saltwater, with a wide variety, typically divided into "Centrales" diatoms and "Pennatales" diatoms. Within each order, there are many "genera," making it quite complex.

The main component of natural diatomite is SiO2, with a content often exceeding 70%. Individual diatoms are colorless and transparent, and the color of diatomite depends on clay minerals and organic matter, among other factors. The composition of diatoms from different mineral sources varies.

Diatomite, also known as diatoms, is a fossilized sedimentary deposit formed from the accumulation of single-celled plant remains over a period of approximately 10,000 to 20,000 years. Diatoms are one of the original life forms on Earth, thriving in seawater or freshwater. It is these diatoms that, through photosynthesis, provide oxygen to the Earth, fostering the birth of humans and animals and plants.

This diatomite is formed from the sedimentary remains of single-celled aquatic plants called diatoms. The unique property of these diatoms is their ability to absorb free silicon from water to form their skeletons. Upon the end of their life cycle, they settle and, under certain geological conditions, form diatomite deposits. It possesses distinctive characteristics such as porosity, low density, large specific surface area, relative incompressibility, and chemical stability. After undergoing processes like crushing, sorting, calcination, air classification, and decontamination to alter its particle size distribution and surface properties, it can be used in various industrial applications, including paint and varnish additives.
