Micro Silica from J M Biotech Pvt Ltd is a high-purity amorphous silicon dioxide (SiO2) powder with particle sizes below 1 micron, supplied for use as a pozzolanic additive in concrete and refractory applications. The material, sourced from the company’s facility in Barddhaman, West Bengal, is processed to achieve a SiO2 content typically above 85%, making it suitable for high-performance construction and industrial uses.
The product is available in densified or undensified forms, with the undensified variant offering higher reactivity due to its lower bulk density (typically 150-300 kg/m³). It is packed in 25 kg bags or 1 MT jumbo bags for export, catering to both small-scale and bulk buyers. The fine particle size and high SiO2 content enhance the mechanical properties of concrete, including compressive strength, abrasion resistance, and durability in aggressive environments.
This silica fume is widely used in India and exported to markets in Southeast Asia and the Middle East for infrastructure projects, precast concrete production, and refractory castables. J M Biotech Pvt Ltd’s location in West Bengal provides logistical advantages for shipments via Kolkata port. Buyers should confirm the material’s compatibility with their specific cement blends and request data on loss on ignition (LOI) and chloride content for quality assurance.

J M Biotech Pvt Ltd is based in Sipta, Mansadanga Gram, Badulia, in the Barddhaman district of West Bengal, India. The company focuses on the production and export of industrial minerals, with micro silica as a key offering. Its location near Kolkata port facilitates efficient logistics for international shipments, particularly to Asian markets.
The supplier’s profile does not provide details on production capacity, certifications, or client references. Buyers are advised to request factory inspection reports and third-party test certificates to verify the consistency of SiO2 content, particle size distribution, and other critical specifications. As a trading entity, J M Biotech Pvt Ltd may source material from multiple producers, so batch-to-batch variation should be anticipated.
Micro Silica, also known as Silica Fume, is a high-purity amorphous SiO2 powder used as a pozzolanic additive in high-performance concrete and refractory applications. With particle sizes below 1 micron and SiO2 content typically above 85%, it significantly improves compressive strength, durability, and chemical resistance of cement-based products. Widely traded internationally for use in construction, ceramics, and specialty coatings, Micro Silica is available in densified or undensified form, packed in 25kg bags or 1MT jumbo bags for export shipment.

Prior to ordering, confirm the SiO2 content, particle size distribution, and LOI through independent testing, as these parameters directly influence the material’s performance in concrete. Request a CoA for each batch and verify whether the micro silica is densified or undensified, as this affects handling and storage. For refractory applications, also check for the presence of crystalline silica, which can compromise thermal stability.
Logistics for micro silica from West Bengal typically involve trucking to Kolkata port for containerised or bulk vessel shipments. Lead times may vary depending on production schedules and port congestion, so buyers should negotiate realistic delivery timelines. Incoterms such as FOB Kolkata or CIF Singapore are standard, but confirm payment terms (e.g., LC at sight) and ensure the supplier provides English-language documentation for customs clearance in the destination country.
Quality control should include testing for bulk density, moisture content, and chloride levels upon arrival. Inspect packaging for damage or moisture ingress, and store the material in dry, sealed conditions to prevent contamination. For large orders, consider third-party inspection during loading and unloading, and retain representative samples for retrospective analysis in case of performance issues.
