Diatomaceous Earth (DE) — scientifically known as Biogenic Amorphous Silica (BASiO₂) — is a naturally occurring sedimentary mineral formed from the fossilised remains of microscopic siliceous algae called diatoms. Over millions of years, these ancient organisms settled on lake beds, their intricate silica shells accumulating into the remarkable mineral we mine today in Far North Queensland.
BSiO₂ Pty Ltd produces non-calcined biogenic amorphous silica — the safest, most natural form of this mineral. Our product is certified by three independent Australian laboratories to meet and exceed Australia's standard for crystalline silica content.
Many people hear "silica" and think of danger. That concern is valid — but it applies to a different form entirely. Understanding this distinction is essential.
