Tribasic Calcium Phosphate—chemically defined as Ca₃(PO₄)₂ or structurally represented by hydroxyapatite Ca₁₀(PO₄)₆(OH)₂ (CAS No. 7758-87-4 / 12167-74-7)—is an essential inorganic phosphate compound manufactured through precise neutralization of thermal-grade phosphoric acid with food- or pharma-compliant calcium hydroxide.
Yanxatech controls the calcination temperature and synthesis stoichiometry to yield specific crystalline allotropes: high-temperature α-TCP (monoclinic, rapid bioresorption for injectable bone cements) and thermodynamically stable β-TCP (rhombohedral, optimal for synthetic bone graft scaffolds and anti-caking matrices).
Through air-classifier jet milling, our particle size distribution (PSD) ranges from sub-micron d50 (1.5–3.5 μm) up to tailored coarse powders. Controlled electrostatic charge prevents agglomeration in dry blending, providing extraordinary moisture absorption capacity (up to 10% w/w) without loss of free-flow kinematics.
Heavy metals (As, Pb, Cd, Hg) and fluorine limits are the critical parameters for pharmaceutical excipients and baby nutrition formulas. Our multi-stage crystallization process limits fluorine to < 50 ppm and lead to < 0.5 ppm, consistently surpassing USP, EP, FCC, and GB standards.

International regulatory revisions across the EU (EFSA) and the United States (FDA) continue to tighten allowable thresholds for lead, cadmium, and arsenic in infant nutrition. Chinese manufacturers with multi-stage crystallization systems will lead this shift.
Detailed technical answers to common queries regarding manufacturing, specification tolerances, packaging, and logistics.
While "Tribasic Calcium Phosphate" is chemically Ca₃(PO₄)₂, industrial and food grades (FCC, E341iii) frequently consist of an amorphous or poorly crystalline hydroxyapatite form, Ca₁₀(PO₄)₆(OH)₂ (Ca/P ratio ~1.67). Pure β-TCP (Ca₃(PO₄)₂, Ca/P ratio 1.50) is formed via high-temperature solid-state reaction or calcination. Yanxatech synthesizes both tailored formulations depending on whether the customer requires high bio-solubility (β-TCP) or optimal powder anti-caking performance (precipitated TCP/HA).
We employ a proprietary thermal-route phosphoric acid process that prevents initial heavy metal contamination often seen in wet-process acid lines. Furthermore, our multi-stage precipitation and crystallization protocols systematically purge lead, cadmium, and arsenic. Every lot destined for infant formulas undergoes Inductively Coupled Plasma Mass Spectrometry (ICP-MS) testing to verify Lead < 0.5 ppm and Arsenic < 0.5 ppm.
Standard packaging comprises multi-ply kraft paper bags with inner heat-sealed polyethylene (PE) liner (25 kg net), or heavy-duty polypropylene woven bulk bags (500 kg / 1000 kg supersacks) with moisture-barrier liners. Stored under dry, clean, and cool warehouse conditions, TCP remains chemically stable with a certified shelf life of 24 to 36 months from the date of synthesis.
Yes. Utilizing air-swept micro-pulverizers and opposed-jet milling systems, we can tailor the D50 between 1.5 microns and 25 microns. A narrow PSD with minimal ultra-fines eliminates bridging inside silo funnels, while tailored ultra-fine grades maximize calcium fortification dispersion in liquid suspensions without grittiness.
Standard stock grades have an MOQ of 1 metric ton (1 pallet). Custom particle-milled or pharma-dossier batches generally require an MOQ of 5 metric tons. Standard delivery time from order sign-off to vessel dispatch from Qingdao or Shanghai port is typically 7 to 14 business days, complete with lot-specific Certificate of Analysis (COA) and GHS-compliant Safety Data Sheets (SDS).
