What Makes Dicalcium Phosphate Dihydrate Different from Anhydrous in Product Development

• - Moisture sensitivity: Dihydrate is less thermally stable above 75°C and may dehydrate under heat.

• - Flow and texture: Dihydrate is microcrystalline and free-flowing preferred in powder mixes and uniform granules.

These differences guide its usage in specific applications where moisture responsiveness or blending behavior is a critical factor.

How is Dicalcium Phosphate Dihydrate used in fertilizer formulations?

Dicalcium Phosphate Dihydrate for fertilizers is valued for its:

• - Rapid phosphorus availability

• - Calcium contribution for pH balancing

• - Granular compatibility in NPK blends

It supports nutrient bioavailability in low-nitrogen fertilizer strategies and is also used in controlled-release soil formulations where hydration-induced conversion to anhydrous form enables nutrient delivery over time.

This makes it especially relevant in regenerative agriculture and nutrient recovery systems.

Is Dicalcium Phosphate Dihydrate suitable for feed or food-grade applications?

Yes. In regulated contexts, USP grade Dicalcium Phosphate Dihydrate is used in:

• - Feed supplements (poultry, cattle, swine)

• - Anti-caking agents for dry powders

• - Leavening systems in baked products

It supports uniform flow and blends well with carrier agents due to its microcrystalline structure.

In feed formulations, it delivers essential phosphorus without contributing excess moisture to the mix important for batch stability in humid environments.

​What should buyers look for when sourcing Dicalcium Phosphate Dihydrate in bulk?

For bulk Dicalcium Phosphate Dihydrate suppliers USA, these are key evaluation points:

• - Grade: Verify whether the product is feed, food (USP/FCC), or fertilizer grade.

• - Moisture Content: Dihydrate typically has ~20-25% loss on ignition due to water content. Confirm this aligns with your formulation needs.

• - Particle Size: Check whether you require powder or custom granule cuts.

• - Documentation: Request CoA, SDS, origin traceability, and particle spec sheets.

Large-volume buyers should align packaging formats (25 kg bags, drums) with warehousing and handling requirements.

What are the key specifications for industrial Dicalcium Phosphate Dihydrate?

Industrial grade Dicalcium Phosphate Dihydrate typically meets the following standards:

• - Assay (as CaHPO4·2H2O): 98–105%

• - Arsenic, Lead, Fluoride: Within ppm-range compliance limits

• - Particle size: 80–200 mesh for powders; 0.5–2 mm for granules

• - Solubility: Slightly soluble in water; aids in predictable release kinetics

For soil and feed applications, buyers should ensure ingredient compatibility with silicates, humic substances, or microbial inoculants.

How does moisture content affect Dicalcium Phosphate Dihydrate storage?

Because it holds structural water, Dicalcium Phosphate Dihydrate is more prone to:

• - Dehydration at elevated temperatures

• - Slight clumping in uncontrolled humidity

Storage guidelines include:

• - Keep in cool, dry conditions

• - Avoid direct heat or sunlight

• - Use lined PP bags with inner PE layer for better protection

These factors are especially important when sourcing in bulk for seasonal production.

What are the regulatory requirements for Dicalcium Phosphate Dihydrate in the U.S.?

In the U.S., Dicalcium Phosphate Dihydrate Powder used in fertilizers, food, or feed must comply with:

• - USDA/AFCO norms for phosphorus and calcium sources

• - USP or FCC grade purity (if used in food/feed)

• - EPA and state-level regulations for heavy metal thresholds (especially in fertilizer blends)

Buyers should confirm that all specifications are third-party verified, and batches meet lot-to-lot consistency.

Can Dicalcium Phosphate Dihydrate be used in fast-release nutrient systems?

Yes. Its hydration profile and water solubility make it a strong candidate in:

• - Starter fertilizers for high phosphorus demand crops

• - Base layers in controlled-release soil mixes

• - Granule coatings where ingredient dispersion matters

Its integration into bioavailable phosphate-based fertilizers also makes it viable in blends where timing and soil activation vary.

Where is Dicalcium Phosphate Dihydrate used in U.S. manufacturing?

Dicalcium Phosphate Dihydrate applications in the U.S. are diverse:

• - Agricultural blends (open-field crops, specialty greenhouse systems)

• - Calcium phosphate dihydrate powder for blending in dry premixes

• - Oral care and personal care manufacturing (as a gentle abrasive)

• - Binder additives in ceramics and polishing compounds

It’s increasingly adopted by manufacturers looking for moisture-sensitive actives and phosphorus control agents.

Conclusion

Dicalcium Phosphate Dihydrate offers a different value profile than its anhydrous counterpart. When used right, it supports product integrity, formulation consistency, and targeted nutrient delivery, all while staying compliant with industry expectations.

For sourcing teams and formulation experts in the U.S., understanding this distinction can help unlock more efficient decisions in bulk procurement and application design.
