Opinions

Why do precipitated and fumed silica grades carry such different price tags in China?

For procurement teams, the practical takeaway is to demand full TDS sheets including carbon content and dispersion test results, not just BET. Running a small-scale trial in your actual resin system before bulk purchase is the only reliable way to validate whether a cheaper domestic grade truly substitutes an import.

How do silica's crystalline and amorphous forms differ in industrial applications?

The distinction matters commercially: crystalline quartz commands premium pricing tied to electronics and optics demand, while diatomaceous earth competes on bulk logistics costs—it's so light that freight charges often exceed material value. Buyers should match the silica form to the actual performance requirement, not just price per ton.

Overview

Diatomaceous earth (diatomite, CAS 91053-39-3) is a soft, porous, lightweight siliceous sedimentary rock composed mainly of amorphous silicon dioxide (SiO₂), with a loose bulk density around 0.47 g/cm³, a melting point above 300°C, and insolubility in water. It serves as a versatile industrial mineral valued for its high porosity, low density, and chemical inertness.

Filtration: used as a filter aid for clarifying beverages, oils, pharmaceuticals, and swimming-pool water.
Construction materials: added to cement, lightweight aggregates, and insulating bricks for thermal and acoustic performance.
Agriculture & animal feed: used as a carrier for feed additives and as a natural pesticide for grain storage.
Industrial absorbents: applied in spill cleanup, cat litter, and as a functional filler in paints, plastics, and rubber.

China is a major producer of diatomaceous earth, with dominant grades used in filtration and construction applications. Domestic supply generally meets demand, with some specialty grades traded internationally. The market is characterised by numerous small-to-medium mines, while downstream processing focuses on calcined and flux-calcined products for higher-value uses.

Key domestic producers:
Jilin Yuanlong – filtration and construction grades.
Yunnan Zhongxing – industrial filter aids and absorbents.
Changbaishan Diatomite – calcined and flux-calcined products.
