DIATOMACEOUS EARTH

​Diatomaceous earth (DE) has important non-toxic chemical characteristics, and distinctive physical properties:

  • Powder containing 80-90% amorphous silica (SiO2)

  • Also contains other essential minerals: magnesium, calcium

  • Absorbent (up to 4 times weight in water)

  • Plant available silica

  • Mild abrasive

  • Porosity (35-65%)

  • Permeability (0.1-10 MD)

  • Low density

  • Low thermal conductivity coefficient

  • Tiny particle size

  • Large surface area

  • Inert chemical reactivity

  • Recyclable, promoting circular economy

Magnesium aluminium phyllosilicate

Chemical formula: SiO2_nH2O

Scientific name: Amorphous silicon dioxide

Our Diatomaceous earth properties:

•    100% natural West Australian Diatomaceous Earth

•    sedimentary rock composed of diatoms, that formed in a freshwater lake over thousands of years

•   consists of geologically-deposited fossilized skeletal remains of siliceous marine organisms and freshwater unicellular species, particularly algae and other diatoms 

•    Diatoms opaline silica skeletal remains of microscopic photosynthetic algae, and can be described as minute, single-celled water organisms.
•    These minute organisms are confined by a glassy crust, formed from the silicon dioxide in its source water. 
•    Compared to other Australian Diatomaceous earth deposits, our West Australian DE is unique:

- originates from freshwater, which is preferred due to being richer in silicon dioxide;

- since it was formed more recently during the Pleistocene to Recent Ages;

- naturally having a higher amorphous silica content.
are also distinctly "boat shaped"

Organics in Diatomaceous earth

•    Hudson Diatomaceous earth is 100% natural with organics

•    Organics include whatever our Diatomaceous earth was naturally formed or over time accumulated together with in the earth, including clay pieces, roots, bark, plant roots, algae remnants, insect remains and pieces, and other plant material.

•    organic matter like roots contributes to its benefits is in its natural composition.

Our Diatomaceous earth is organic raw ore.

Diatomaceous earth can be used in its organic raw ore form.

Screened, processed, milled and calcined Diatomaceous earth require processing which is suitable for numerous applications
