Types of Diatomaceous Earth

 
Damolex N (non-calcined Diatomaceous Earth) is used as an absorbent and as a desiccant. It is available as a fine powder.

Damolex C (calcined Diatomaceous Earth) products are used as carriers and as absorbents. Damolex C is available in several different granule sizes: 0.2-0.6mm, 0.5-1mm, 1-3mm and 3-6mm.  It is also available as a 200 mesh powder.

CelTix is a Food Chemicals Codex (FCC) grade diatomite, rich in amorphous (non-crystalline) silica and low in aluminium, iron and other metals.  It is from a fresh water source.

Technical Background

 
Diatomaceous Earth is an absorbent mineral formed from the remains of diatoms, and is composed mainly of amorphous (non-crystalline) silica.  Alternative names include diatomite and kieselguhr. 
 
Diatoms are microscopic unicellular algae of the phylum Bacillariophyta, and can occur in marine or fresh water. Structurally in two halves – hence their name - their cell walls are impregnated with silica which builds up into large beds.  Diatomaceous earth is therefore found close to the sites of current or former water bodies.

Calcined diatomaceous earth has been processed by heating to a high temperature, converting much of the amorphous silica into crystalline forms.  This improves the mineral's absorption properties, and enables the manufacture of robust granules which won't break down when they become wet.
