Diatomit Ziemia Okrzemkowa Diatomit 10kg

diatomaceous earth (Diatomite) 10 kg / 20 L
Other Names: Diatomaceous earth, Kieselguhr, Diatomite

General Information:
Diatomaceous earth  is a naturally occurring, soft, siliceous sedimentary rock composed mainly of fossilized diatom skeletons. It is characterized by its lightweight, porous structure and high content of amorphous silica. Produced according to Polish Standard BN-91/0568-01, it is a safe, non-flammable, odorless material widely used in filtration, construction, and industrial applications.

Chemical Composition:

• SiO₂ (Silicon Dioxide): minimum 68%

• Al₂O₃ (Aluminum Oxide): maximum 12%

• Fe₂O₃ (Iron(III) Oxide): maximum 7%

Physical and Chemical Properties
Appearance: White to light gray fine powder or granules
Odor: Odorless
Density: Light and porous (bulk density varies between ~150–250 kg/m³)
Melting Point: >1000°C (depending on impurities)
Solubility in Water: Insoluble
pH (suspension in water): Slightly alkaline (pH 7–9)

Applications
Filtration:

• Used as a filtration aid in water purification, food production, and industrial processes.

Construction Materials:

• Incorporated into lightweight concrete and thermal insulation materials.

Industrial Absorbents:

• Applied for absorbing oils, chemicals, and spills in industry.

Agriculture and Horticulture:

• Used as a soil conditioner and pest control agent (mechanical insecticide).

Material Science and Research:

• Studied for its porous structure and high surface area in advanced material development.

Key Properties

• Natural Origin: Extracted without chemical additives.

• Safety: Non-toxic, non-flammable, environmentally friendly.

• High Porosity: Excellent for filtration and absorption purposes.

• Lightweight: Low bulk density makes it easy to handle and transport.

Handling and Storage
Storage Conditions:

• Store in a dry, cool, and well-ventilated place.

• Protect from moisture and mechanical damage.

• Keep containers tightly closed to prevent dust formation.

Handling Precautions:

• Avoid dust generation during handling.

• Use standard PPE, including dust mask and gloves, when dealing with large quantities.
