Uses: filter medium (eg clarification of syrups and beer), as an absorbent (eg cat litter and industrial spillage granules), as an insecticide (due to its abrasive properties), and as a filler in products such as paper and paints.
Diatomaceous Earth is an absorbent mineral formed from the remains of diatoms, and is composed mainly of amorphous 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.
Our calcined diatomaceous earth is available in a choice of three sizes: 0.2–0.6, 0.5–1.0 and 1–3mm. We also stock a dried powdered diatomaceous earth (<45 microns) and other grades are available by special order.
