Microsilica (silica fume)
Microsilica from Metalumana is a highly reactive pozzolanic material produced as a byproduct of silicon metal and ferrosilicon alloy smelting. It contains 85-98% SiO2, making it an effective additive for high-performance concrete, refractory linings, and specialty ceramics. The material’s fine particle size, typically under 1 micron, enhances compressive strength and durability in construction applications.
This silica fume is supplied in its raw, unprocessed form, with bulk density and moisture content critical for quality assessment. Industry-standard microsilica often exhibits a bulk density of 200-700 kg/m³ and moisture content below 3%, though buyers should confirm exact values with the supplier. Loss on ignition (LOI) is another key parameter, typically under 2% for premium grades, ensuring minimal organic impurities.
Primary buyers include concrete producers, refractory manufacturers, and ceramic specialists seeking to improve material performance. For import, verify compliance with ASTM C1240 or EN 13263 standards, which define microsilica for concrete use. Packaging is usually in 25 kg or 1-ton bulk bags, with incoterms and lead times negotiated per shipment.

Microsilica, also known as silica fume, is a highly reactive pozzolanic material produced as a byproduct of silicon metal and ferrosilicon alloy smelting. With SiO2 content typically exceeding 85-98%, it is widely used as a concrete additive to improve compressive strength, durability, and chemical resistance, and as a critical raw material in refractory linings and specialty ceramics. For international buyers sourcing microsilica for construction materials or industrial applications, understanding bulk density, moisture content, and loss on ignition (LOI) specifications is essential for quality assessment and import compliance.

Sourcing Microsilica (silica fume) from Metalumana - United Arab Emirates Import Guide
Before ordering microsilica from Metalumana, confirm the SiO2 content, particle size distribution, and LOI values, as these directly impact performance in concrete or refractory applications. Request a certificate of analysis (COA) for each batch to ensure consistency with your project requirements.
Logistics arrangements should account for the material’s low bulk density, which may require specialized handling to avoid dust generation. Discuss incoterms such as FOB Sharjah or CIF destination port, and clarify payment terms (e.g., TT or LC). Lead times often depend on production schedules and shipping availability.
For quality assurance, conduct on-site inspections or third-party testing for compliance with ASTM or EN standards. Verify that packaging meets international shipping regulations, particularly for moisture-sensitive materials. Documentation should include COAs, MSDS, and origin certificates to facilitate customs clearance.
