Other grades are available on request; please contact your representative for further information.

Mulcoa Packaging

Our materials are available in 25kg paper sacks, 1000kg bulk bags, or as bulk as standard.

Applications

Mulcoa is a high mullite chamotte produced by calcining low alkali clays for consistent quality and chemistry. LKAB Minerals supplies Mulcoa in various grades, including 5-8mm, 3-5mm, 1-3mm, 0-1mm, 0-250μm, 0-150μm, and 0-15μm, for use in manufacturing high-quality fired and monolithic refractory products. Some key applications include:

Ceramic tiles & bricks

• Used as a raw material in the production of ceramic tiles and bricks for its high thermal stability and strength.
• Enhances the durability of ceramics subjected to high temperatures during the firing process.

Refractory materials

• Employed in the manufacture of refractory bricks and mortars for industrial furnaces and kilns.
• Provides excellent thermal resistance and maintains structural integrity in high-temperature environments.

Industrial ceramics

• Essential in producing ceramics for applications such as kiln linings and industrial insulation.
• Improves the resistance of ceramics to wear, thermal shock, and chemical corrosion.

Monolithic refractories

• Used in the production of monolithic refractories like castables and plastic refractories.
• Mulcoa’s high mullite content ensures superior resistance to thermal cycling and molten metal attacks in industrial applications.

Clay-based ceramic products

• Incorporated into clay-based products such as ceramic pipes, sanitary ware, and electrical insulators.
• Its consistent chemistry and quality improve the thermal and mechanical properties of the final ceramic product.
