Diatomite is formed by remains of unicellular water plant-diatom which is a non-renewable resources.
The chemical composition of diatomite is SiO2, and the SiO2 content determine diatomite’s quality. ,the more the better.
Diatomite has some unique properties, such as porosity, lower density, and large specific surface area, relative
incompressibility and chemical stability. It has poor conductivity for acoustics ,thermal, electrical, non-toxic and tasteless.
