About Us

More than 45 years of mastering silica chemistry

Some companies make chemicals. A few understand them down to the last nanometre. DKIC is one of those few.

For more than 45 years, DKIC Pvt. Ltd. (formerly Dr. Khan Industrial Consultants Pvt. Ltd.) has focused on one discipline: silica. Today we are India’s largest manufacturer of colloidal silica, with a licensed capacity of 36,000 tonnes per annum, and India’s exclusive manufacturer of Ethyl Silicate-40 and Tetraethyl Orthosilicate (TEOS), with a licensed capacity of 7,200 tonnes per annum.

Behind those numbers is a simple belief we have held since day one: if you understand the chemistry deeply enough, you can make any grade the market needs, to the exact specification.

Built by scientists, run by engineers

DKIC was founded by the Late Dr. M. A. Ghaffar Khan, a chemical engineer with a Ph.D. from IIT Bombay and a former CSIR scientist. In 1980 his work made DKIC the first company in India to produce colloidal silica in commercial quantities, replacing imports, and laid the scientific foundation of the company.

Today DKIC is led by a second generation of technocrats. Managing Director Dr. Vikhar A. Khan, a chemical engineer with a Ph.D. from the USA, leads production, R&D and modernisation, and Marketing Director Mr. Mudit Kumar Agarwal leads domestic and international sales.

This is not a trading house or a contract filler. It is a family of chemists and process engineers who design their own plants, run their own reactions and solve their own problems. When a customer’s requirement changes, the people who answer the call are the ones who understand the reaction.

Our history

• 1980 – DKIC becomes the first company in India to produce colloidal silica in commercial quantities.

• 1982 – The company is incorporated.

• 2000 – Commercial production of Ethyl Silicate-40 and TEOS begins.

• 2006 – Ethyl silicate production moves to a new generation of process technology.

• 2021 – DKIC acquires Niki Ceramics Pvt. Ltd.

• 2022 – DKIC acquires Chemco Stilbene Ltd.

Infrastructure and quality

Our factory is in Lote Parshuram MIDC, District Ratnagiri, Maharashtra, a government-designated chemical zone, with dedicated plants for colloidal silica (12,000 m² plot) and ethyl silicates (13,000 m² plot), each with its own effluent treatment plant licensed by the Maharashtra Pollution Control Board. Our own fleet of 12 trucks delivers across India.

The factory QC laboratory tests every raw material, work-in-process material and finished batch, using Sears surface area, dynamic light scattering and laser-diffraction particle sizing, flame photometry and ICP-OES. Every dispatch carries a Certificate of Analysis, and a retained sample is kept for three months.

Trusted by multinationals, in India and abroad

DKIC is a registered vendor to many multinational companies operating in India, and we supply customers in international markets. Multinationals choose DKIC for:

• Scale: India’s largest colloidal silica capacity

• Range: nearly every commercial grade under one roof

• Precision: grades matched to the most demanding international benchmarks

• Technology: modern, chlorine-free TEOS and ES-40 production

• Expertise: direct technical support from the chemists who make the product

• Reliability: more than 45 years of consistent supply

Looking ahead

Our R&D centre in Navi Mumbai continues to explore new frontiers for silica, including advanced construction chemicals, agricultural silicon nutrition, electronic-grade colloidal silica and high-purity precursors for emerging technologies. New colloidal silica and TEOS plants are planned at our recently acquired sites. More than four decades in, our curiosity about silica is as strong as ever.
