Micro Silica
MR Mark Overseas supplies MARKCHEM Micro Silica, an amorphous silicon dioxide (SiO2) product with purity levels ranging from 85% to 98%. Sourced from silicon metal and ferrosilicon production in Karnal, Haryana, this ultra-fine material reacts with calcium hydroxide in cement to form calcium silicate hydrate (CSH), significantly boosting concrete strength and durability. The product is traded globally, with export packaging options including bulk bags and drums.
The fine particle size, typically below 1 micron, ensures rapid pozzolanic activity, leading to denser concrete matrices with reduced permeability and enhanced resistance to chemical attacks. In refractory applications, micro silica improves thermal stability and mechanical strength, making it suitable for high-temperature environments. Standard industry grades for micro silica in construction often specify SiO2 content, particle size, and loss on ignition as key parameters.
Primary markets for this product include high-strength concrete producers, refractory manufacturers, and construction chemical suppliers. Buyers in infrastructure, oil and gas, and precast concrete sectors use micro silica to meet stringent performance requirements. Importers should confirm the supplier’s ability to provide consistent quality, as well as compliance with international standards for silica fume in concrete.

Sourcing Micro Silica from MR Mark Overseas - India Import Guide
Prior to ordering from MR Mark Overseas, confirm the SiO2 content, particle size distribution, and loss on ignition for the intended batch. Request compliance documentation for ASTM C1240 or EN 13263 to ensure the micro silica meets the required standards for your application, whether it be concrete, refractory, or another use case.
Logistics for micro silica shipments should account for its fine particle size, which necessitates secure packaging to prevent dust emissions. Discuss Incoterms such as FOB or CIF with the supplier to clarify responsibilities for freight, insurance, and export customs. Lead times may depend on production and shipping schedules, so plan accordingly.
Upon delivery, perform quality checks to verify SiO2 purity, moisture content, and particle size against the COA. Inspect packaging for damage, as compromised bags can lead to contamination or material loss. Ensure the MSDS is provided to comply with local regulations for the safe handling and storage of amorphous silica.
