Diatomite powder, a remarkable natural substance, traces its origin to the tiny yet mighty diatoms, single - celled algae that
have thrived in aquatic environments for millions of years. Diatoms possess intricate cell walls made primarily of silica, giving them unique and often beautiful microscopic structures.
These microscopic organisms live in various water bodies, including oceans, lakes, and rivers. In the ocean, they are a crucial part of the marine food web, serving as a primary source of food for numerous marine creatures. In freshwater settings like lakes, they also play a vital role in maintaining the ecosystem's balance.
As diatoms die, their silica - rich cell walls sink to the bottom of the water bodies. Over an extended period, sometimes spanning millions of years, countless layers of these cell walls accumulate. In marine environments, the continuous deposition of diatom remains, along with other sediments, occurs at a slow but steady pace. In freshwater lakes, especially those with stable conditions, the accumulation can also be significant.
Under specific geological conditions, these accumulated layers undergo compaction and cementation. Pressure from the overlying sediments squeezes out the water and air between the diatom cell walls, packing them tightly together. Minerals dissolved in the water may also act as cementing agents, binding the cell walls and further solidifying the deposit. This process transforms the loose sediment of diatom remains into diatomite, a soft, chalky, sedimentary rock.
To obtain diatomite powder, the mined diatomite rock is processed. The raw diatomite is first crushed to break it into smaller pieces. Then, through grinding and milling, it is refined into a fine powder. Depending on the intended use, additional purification steps may be involved to remove impurities such as clay, sand, and organic matter. These purification methods can include washing, drying, and sometimes chemical treatments.

The advantages of diatomaceous earth are mainly manifested in the following aspects:
Stable physicochemical properties: Diatomaceous earth is chemically stable, abundant in reserves, and inexpensive. It is also non-toxic, harmless, and environmentally friendly.
Excellent adsorption performance: Diatomaceous earth is lightweight and porous, with a porosity as high as 90%. Therefore, it has strong adsorption capabilities, which can be used to remove suspended matter, heavy metal ions, bacteria, and organic pollutants in water, thereby improving water quality. Additionally, its porous nature helps improve soil structure by enhancing soil aeration and water retention.
Good thermal and sound insulation properties: Diatomaceous earth exhibits excellent thermal insulation and moisture absorption properties, making it suitable for use as wall materials, floor fillings, and sound insulation materials.
Versatile applications: Diatomaceous earth has a wide range of applications in fields such as building energy efficiency, agriculture, water treatment, food and chemical industries. It can also serve as a filler in fiberglass, rubber, and plastics, a filler in papermaking, a matting agent in paints, and a carrier for pesticides and compound fertilizers.
