5) Production Routes & Process Controls
DCP can be manufactured via neutralization and precipitation steps using calcium and phosphate sources, followed by filtration, washing, drying, and milling/granulation.
The process window determines crystal hydration, particle structure, and impurity carryover. Robust controls are essential for predictable quality.
Raw Material Control
Verified purity of calcium and phosphate inputs minimizes downstream contaminants and improves nutrient guarantees.
Thermal & Hydration
Drying parameters and hydration state influence stability and flow; dihydrate vs anhydrous selection depends on application.
Milling & PSD
Controlled milling and classification produce consistent PSD, enabling reliable handling, tableting, and dispersion.
Process consistency + analytical discipline = fewer deviations, faster batch release, and lower total cost-in-use for the buyer.
