High-grade diatomite is a high-value eco-friendly mineral upgraded via ultra-purification, precise calcination, and micronization With SiO₂ ≥90%, ultra-low heavy metals (Pb<2 ppm), complete diatom frustule structure, and controlled porosity (85–90%), it meets strict international standards (FDA food contact, REACH, RoHS, USP) for food/beverage filtration, pharmaceutical processing, high-end cosmetics, and green building exports. Its integrated strengths—high filtration efficiency, strong adsorption, chemical purity, thermal stability, and low carbon footprint—make it a core material for global food safety and sustainable manufacturing

Premium Grades & Advanced Processing

• Food-Grade Calcined Diatomite: 800–900°C high-temperature calcination, SiO₂ ≥92%, whiteness ≥88%, for beer, wine and edible oil filtration.
• Pharmaceutical-Grade Purified Diatomite: Acid-leached & high-purity processed, heavy metals <1 ppm, sterile, for antibiotics, injections and oral preparations
• Surface-Modified Diatomite: Hydrophobic/hydrophilic tailored, enhanced adsorption capacity, for cosmetics, air purification and catalyst carriers.

Key High-End Applications

Food & Beverage Safety Filtration

• Beer & Wine: Removes yeast, proteins and colloids; improves clarity, flavor stability and shelf life.
• Edible Oil & Syrup: Decolorizes, filters impurities, and reduces peroxide value; meets food hygiene standards.

Pharmaceutical & Cosmetic Manufacturing

• Pharmaceutical Processing: Filter aid for antibiotics, vitamins and traditional Chinese medicine extracts; low impurity, no API interaction赤峰市元宝山区人民政府.
