Flux-Calcined Diatomaceous Earth

Flux-Calcined Diatomaceous Earth

Flux-Calcined Diatomaceous earth is produced from carefully selected high-purity diatomaceous earth through high-temperature calcination, endowing it with exceptional thermal stability and a porous structure. With a SiO₂ content ≥85%, uniform pore size distribution, and a specific surface area of 40–60 m²/g, this product is ideal for applications in food, beverage, pharmaceutical, and chemical industries.The calcination process is environmentally friendly and non-toxic, complying with industrial safety production standards. Available in customizable particle sizes (20–1200 mesh), it adapts to diverse production requirements. Leveraging its high porosity and low density, flux-calcined diatomite helps customers achieve energy-efficient operations and enhanced product quality.

What are the Advantages of Flux-Calcined Diatomaceous earth?
1.Efficient Fluxing Performance: High-purity SiO₂ (≥85%) and a uniform microporous structure synergistically reduce material melting temperature (by ~10-15%), enhance melt fluidity, shorten processing cycles, and lower energy consumption. 2.Exceptional Thermal Stability: Calcined at 850–1200°C, it exhibits strong high-temperature resistance with minimal volumetric shrinkage (≤5%), preventing cracking or structural collapse. 3.High Adsorption & Low Impurities: Porosity >65% and a specific surface area of 40–60 m²/g enable efficient adsorption of molten impurities (e.g., metal oxides, ash), improving product purity by over 20%. 4.Energy-Efficient & Eco-Friendly: Replaces traditional fluxes (e.g., cellulose) to reduce fluoride pollution. The calcination process emits no harmful gases, complying with RoHS and REACH standards for sustainable production. 5.Versatile Adaptability: Customizable particle sizes (20–1200 mesh) suit diverse applications, including food, beverages, pharmaceuticals, chemicals, ceramic glazes, and refractory materials. 6.Cost Optimization: Low dosage (0.5–3% recommended) delivers significant effects, cuts raw material waste, reduces overall costs by 15–30%, and extends equipment lifespan. Flux-calcined diatomite combines advanced processing with industrial innovation, balancing performance enhancement and sustainable development goals.
