Diatomite or diatomaceous earth is a sediment greatly enriched in biogenic silica in the form of siliceous skeleta of diatoms, a diverse array of microscopic, single-cell algae These frustules are sufficiently durable to retain much of their structure through long periods of geologic time and through thermal processing Diatomite products have an inherently intricate and highly porous structure composed primarily of silica
A rock, high in amorphous silica content, formed from the structures of tiny fresh- and salt-water organisms called diatoms Diatomite has several commercial uses
Diatomite, or diatomaceous earth, is a siliceous sedimaentary rock formed from the accumulations of diatoms or other nanoplankton
