In recent years, the United States, Denmark, and Japan have been the leading exporters of diatomite, collectively accounting for a substantial share of global supply, while China, the United States, and Germany ranked among the top importers—reflecting both domestic consumption and re-export activity. Diatomite prices have remained relatively stable amid moderate demand growth across filtration, construction, and agricultural end uses. Export volumes from Denmark and Japan have shown consistent growth since 2022, while U.S. trade flows—both exports and imports—have remained dominant and largely stable.
Diatomite (CAS 61790-53-2) is a naturally occurring, porous, amorphous silica-based sedimentary rock composed primarily of fossilized diatom frustules; it typically appears as a fine, lightweight, off-white to light gray powder with no odor and negligible volatility. Chemically, it is classified as a hydrated amorphous form of silicon dioxide (SiO₂·nH₂O), not an organic compound or synthetic intermediate. It is widely used as a functional filler, filter aid, and mild abrasive across industrial applications—notably in filtration systems for beverages, pharmaceuticals, and wastewater treatment, as well as in paints, coatings, plastics, and agricultural formulations. Its high porosity, low density, and inertness make it suitable for performance-enhancing roles in polymer composites, catalyst supports, and animal feed additives.
Chemically,diatomaceous earth is mostly amorphous silicon dioxide,accompanied by mineral salts, with large surface area.Its use as an insecticide dust is based on its capability toabsorb moisture, oils, and waxes (48).
