Product Overview
Silicon dioxide (SiO₂, CAS 7631-86-9) in our catalog means engineered silica — precipitated or fumed grades for rubber, coatings, toothpaste-adjacent industrials and anti-caking — not a truck of river sand. Drashti Chemicals Vadodara matches form to your last successful grade code.
Precipitated and fumed silicas both read “SiO₂” on a headline but behave differently in viscosity, reinforcement and dusting. Sending “silica 25 kg” without BET surface area or grade code is the fastest way to fail a compounding trial.
Typical HSN 28112200 appears on many industrial silica invoices — confirm on yours. COA should show SiO₂ dry basis, moisture, and the physical markers your process controls (DBP, BET, pH of slurry as relevant).
Packs are bagged and must stay dry. WhatsApp form, grade code and kg — no list prices. We are a stockist with documented lots, not a furnace claiming every silica chemistry.
If you need filter sand media or magnesium silicate filler instead, those are separate product pages — use them rather than stretching this SiO₂ SKU into a doorway for every white powder.

Frequently Asked Questions
Do you supply silicon dioxide / silica from Vadodara?
Yes. Precipitated, fumed and industrial silica paths as stocked. Send grade code or BET on WhatsApp.
Precipitated vs fumed silica?
Different structure and thickening behaviour. They are not drop-in swaps in rubber or coatings.
Is SiO₂ the same as quartz sand?
Same chemistry family, different particle engineering. Filter sand and precipitated silica are different SKUs.
Typical HSN?
Silicon dioxide often ships under 28112200 — confirm on invoice.
Do you publish prices?
No. RFQ with form + kg.
