Metakaolin

Metakaolin is a highly reactive mineral admixture, typically appearing as a white powder. It is produced by calcining kaolin at high temperatures (500–900°C), exhibiting good dispersibility, chemical stability, and strong adsorption properties.

Formula:: Al₂O₃·2SiO₂
CAS:: 15123-81-6
Min. Order:: 25KG
Appearance:: White powder
Application:: Construction:
High-Performance Concrete: Used as a mineral admixture to enhance strength, durability, and crack resistance of concrete.
White Cement: Improves color and performance of white or colored cement.
Insulating and Waterproof Mortar: Enhances thermal insulation and waterproof properties of mortar.
Refractory Materials: Improves refractoriness and stability of refractory products.

Ceramic Industry:
Ceramic Materials: Enhances strength and wear resistance of ceramics.
Geopolymer Coatings: Improves adhesion and durability of geopolymer coatings.

Coatings Industry:
Filler and Thickener: Enhances suspension and stability in coatings.
Pigment: Produces white pigments with high whiteness and good opacity.

Other Applications:
Medical Rubber Fillers: Enhances wear resistance and stability of medical rubber products.
Cable Fillers: Improves insulation properties in cable insulation layers.
PVC Cable Sheaths: Acts as an acid scavenger and insulating additive to enhance cable performance.
Packaging:: Typically supplied in 25 kg bags with an inner polyethylene lining and outer woven or laminated paper bag. Custom packaging available upon request.
Storage:: Store in a dry, ventilated, and clean warehouse, away from direct sunlight and moisture. Keep sealed to prevent moisture absorption. Keep away from ignition sources and strong oxidizing agents. Avoid contact with acids, bases, and combustibles. Periodically inspect packaging for integrity to ensure no leakage or caking.
Transportation:: Use dedicated, well‑sealed vehicles to transport Metakaolin, avoiding mixing with other items. Inspect packaging integrity before transport and replace any damaged packaging. Maintain smooth transport to prevent vibration and impact damage. Personnel should wear protective equipment, including gas masks, chemical safety goggles, corrosion‑resistant clothing, and rubber gloves.
Summary:: Metakaolin is a highly reactive mineral admixture widely used in construction, ceramics, coatings, and cable industries. It enhances strength, durability, and performance of concrete, ceramics, and coatings. Proper moisture‑resistant packaging and storage in dry, ventilated conditions are essential to maintain product quality and prevent caking.
