What is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring sedimentary rock composed of the fossilized remains of diatoms, a type of algae. It is highly porous and has a delicate, powdery texture. Diatomaceous earth is known for its high silica content, which gives it a range of unique properties and applications.

Definition

Diatomaceous earth, often referred to as DE, is a soft, light-colored rock primarily composed of the fossilized remains of diatoms. These microscopic aquatic plants lived millions of years ago and left behind their exoskeletons when they died. These exoskeletons accumulate over time, forming large deposits of diatomaceous earth.

Formation

The formation of diatomaceous earth begins with the growth and death of diatoms in bodies of water such as oceans, lakes, and rivers. As these diatoms die, their silica-rich exoskeletons sink to the bottom of the water body and are eventually covered by sediment. Over time, the pressure from the layers of sediment transforms the diatom remains into a solid rock known as diatomaceous earth.

Types

There are two primary types of diatomaceous earth: food-grade and industrial-grade. Food-grade diatomaceous earth is used in applications that involve direct contact with humans and animals, such as pest control and food processing. It is processed differently to remove impurities and is considered safe for consumption. On the other hand, industrial-grade diatomaceous earth is used in various industrial applications like filtration and abrasive products.
