Diatomite is a highly porous silica-rich material mainly composed of diatom shells. Even though the shells are porous themselves, the remarkably high porosity of diatomite is due to the open spaces present between the diatom shells composing the rock. The porous structure of diatomite makes it a poor conductor of heat and a good insulator.
