Diatomaceous Earth (Dicalite USA)

What is Diatomaceous Earth?

Diatomaceous Earth (DE) is a naturally occurring, soft, siliceous sedimentary rock composed of the fossilized remains of microscopic aquatic algae called diatoms. These unique organisms have hard cell walls made of silica, forming intricate and porous structures.

Rich in amorphous silica, DE is widely recognized for its exceptional porosity, filtration capabilities, and absorbent properties. When processed, it becomes a fine, white powder that is non-toxic, chemically inert, and eco-friendly—making it ideal for both industrial and food-grade applications.

Used extensively across sectors like food and beverage, pharmaceuticals, agriculture, and water treatment, Diatomaceous Earth is a trusted solution for effective and sustainable filtration and processing.

These characteristics make Diatomaceous Earth a preferred choice as a filter aid, absorbent, anti-caking agent, insulating additive, and abrasive across sectors like food processing, water treatment, agriculture, pharmaceuticals, and more

Properties and Benefits

Diatomaceous Earth (DE) possesses a unique combination of physical and chemical properties that make it ideal for a wide range of industrial applications. Its naturally porous structure and high silica content are key to its exceptional performance.

  • Color: White to off-white
  • Odor: Odorless
  • Form: Powdery to granular
  • Porosity: Extremely high, due to its unique 3D microscopic pore structure
  • Composition: Primarily amorphous silica (SiO₂), with traces of alumina and iron oxide
  • pH Level: Neutral to slightly alkaline
  • Density: Low (typically 160–350 g/L, varies by grade)
  • Moisture Content: Very low (generally less than 1%)
  • Unique 3D morphology for enhanced filtration
  • High porosity and low density for effective particle capture
  • Excellent absorption capacity for oils, liquids, and chemicals
  • Large surface area for increased contact efficiency
  • Chemically inert and safe for sensitive applications
  • Natural anti-caking agent for powders and dry products
  • Effective insulating properties in high-temperature applications
  • Acts as a mild abrasive in personal care and polishing products

These characteristics make Diatomaceous Earth a preferred choice as a filter aid, absorbent, anti-caking agent, insulating additive, and abrasive across sectors like food processing, water treatment, agriculture, pharmaceuticals, and more
