Everyone is likely familiar with diatom mud. As living standards improve, people place great importance on environmentally friendly home decoration, which is why this new type of wall material made from diatom mud has gained widespread popularity in the market thanks to its excellent environmental benefits. One of the main raw materials for diatoms is diatomite. So, how is diatomite formed? Linjiang Xinghui Diatomite Filter Aid Co., Ltd. will provide you with a detailed explanation on this topic. I. The formation of diatomaceous earth Diatomaceous earth originated from planktonic organisms called diatoms, which are single-celled algae that lived in water hundreds of thousands of years ago. Diatoms are extremely widespread and can be found in oceans, freshwater, brackish water, soil, and moist surfaces. Most live in the open ocean waters; of course, some live on the seabed sediment like membranes, and there are even species that can survive in merely humid air. The diatoms that form diatomite minerals mainly come from the ocean. During their growth, diatoms continuously absorb free silicon from the water to form porous and robust cell walls. Once their life cycle comes to an end, these cell walls do not decompose; instead, they settle on the bottom of the water. Over hundreds of thousands of years, through accumulation and changes in the Earth’s crust, these cell walls give rise to diatomite. II. Characteristics of diatomite Diatomite is a siliceous rock; since it is formed through the accumulation and transformation of ancient diatom remains, it also belongs to the category of biogenic siliceous sedimentary rocks. Its chemical composition is primarily SiO2, and its chemical and physical properties are stable; this is also the main reason why diatomite can have a service life of up to 20 years when used to make diatomaceous earth. At the same time, diatomite is porous, with a porosity of over 90%; the number of micropores in it is thousands of times that of activated carbon. This unique structure is what we refer to as a \"molecular sieve,\" and it possesses strong adsorption capabilities. When diatomite is carefully processed into diatomaceous earth, this unique structure is preserved intact, making it difficult for harmful gas molecules such as formaldehyde and benzene compounds in the air to escape this effective filtering mechanism. The above is an introduction to how diatomite is formed. I hope it can be helpful to everyone.
