Our Core Material
Diatomaceous earth, a substance composed of fossil diatoms
A diatom is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world.
Diatom boards are a new generation of equipment and decoration materials made from food-grade polymer resin and diatom opal. Diatoms are single-celled aquatic algae that live in the ocean and produce 70% of the Earth's oxygen. During their growth, free silicon in the water is absorbed to form a solid and porous cell wall, which remains after the diatom's life cycle is complete and further forms diatomite due to crustal changes. Diatom opal is an important marine biological mineral resource derived from diatomite formed by diatom growth metabolites and geological processes. Over millions of years, diatoms have developed three-dimensional porous diatom opals through genetic control.
​
Diatoms are one of the most successful photosynthetic planktonic organisms in the ocean and they play a major role in the biogeochemical cycle of carbon, silicon, and other elements. Their photosynthesis accounts for more than one-fifth of the global ecosystem, more than all of the tropical rainforests on the planet combined. Diatoms are also one of the few aquatic organisms that can absorb silicon to build their cell wall, made of type A opal. This means that their life activities and the fate of their siliceous remains are the main links in the global carbon-silicon cycle.
​
In the realm of oil and gas resources, sediments that are rich in diatom remains form sedimentary rocks replete with micropores after a long geological process, often connected to the process of oil and gas accumulation. Diatomite ore has billions of tons of global reserves, and diatom opal is one of the most widely used non-metallic minerals due to its unique porous micro-nano structure, strong adsorption capabilities, and heat and acid resistance.
​
Diatom opal has a number of mechanical, optical, photoexcitation properties, and biocompatibility that make it suitable for a variety of applications. It has been used for heavy metal adsorption, lithium ion batteries, supercapacitors, solar cells, hydrogen storage, heat storage, drug delivery and release, tissue engineering, coagulants, and biosensors. It has great potential in environmental protection, nano-energy, biomedicine, and other industries such as chemicals, petroleum, and building materials.
