Diatom is a powder, non-metallic mineral composed of the fossilized skeletal remains of microscopic single-celled aquatic plants called diatoms. Over 10,000 species of these microscopic Algae have been recognized, each with its own distinct shape, ranging in size from under 5 microns to over 100 microns.
Diatom deposits are usually categorized based upon their fresh water or salt water origin. Both the chemical composition and the physical structure of diatomite make it of great commercial value for a wide spectrum of uses, including filter aids, functional fillers, carriers for active ingredients and diluents, and aggregates.
Diatom has also found value as an insulating material in high-temperature mechanisms like furnaces and boilers. It has also proven effective as a sound insulator.
