The chemical formula of tricalcium phosphate, denoted as Ca₃(PO₄)₂, represents a vital compound in the realm of industrial manufacturing, food additives, feed supplements, and pharmaceutical intermediates. This inorganic salt is composed of three calcium ions (Ca²⁺) and two phosphate ions (PO₄^3-), forming a stable crystalline structure with a molecular weight of approximately 310.18 g/mol. Its white, odorless powder form makes it highly versatile for B2B applications, particularly in English-speaking regions like the USA where stringent FDA regulations demand high-purity sources.

Understanding the chemical formula of tricalcium phosphate begins with its synthesis. Primarily produced via the reaction of phosphoric acid (H₃PO₄) with calcium hydroxide (Ca(OH)₂) or calcium carbonate (CaCO₃), the process follows:
3Ca(OH)₂ + 2H₃PO₄ → Ca₃(PO₄)₂ + 6H₂O. This precipitation method ensures high purity, especially when using premium corn starch-derived raw materials in fermentation processes, as practiced by manufacturers like Shijiazhuang Standard IMP&EXP CO.,LTD.

The crystal structure of tricalcium phosphate Ca₃(PO₄)₂ is predominantly whitlockite (β-TCP) or hydroxyapatite-related phases, with solubility governed by pH—minimal in neutral water (Ksp ~10^-29) but increasing in acidic environments. This property is crucial for its role as a calcium phosphate supplement. Thermally, it decomposes above 1,200°C into calcium pyrophosphate and lime, making it stable for high-heat processing in animal feed extrusion.

In food applications, the chemical formula of tricalcium phosphate enables its use as an anti-caking agent (E341(iii) in EU), acidity regulator, and nutrient fortifier. For instance, in baking powders, it reacts slowly with sodium bicarbonate to release CO₂, ensuring consistent rise without bitterness. FDA approves it up to 5% in flour, with GRAS status affirming safety. Its bioavailability as a calcium source is 25-30%, superior to some carbonates, aiding bone health in fortified dairy and cereals targeted at USA markets.

For feed additives, Ca₃(PO₄)₂ formula supplies 38-40% phosphorus and 20% calcium, addressing deficiencies in poultry, swine, and ruminant diets. AAFCO standards require minimum 16% phosphorus content, which our food-grade and feed-grade variants exceed. Studies from the Journal of Animal Science (2022) show 15% feed efficiency gains when replacing dicalcium phosphate, reducing costs by 12% per ton.

Pharmaceutically, the formula supports tablet excipients due to low reactivity and compressibility. In toothpaste, it acts as a mild abrasive (particle size 1-5μm), polishing enamel without wear (RDA <50). Its biocompatibility extends to bone grafts and dental implants, where β-TCP resorbs at 20-30μm/year, promoting osteogenesis per ISO 10993 testing.

Spectroscopically, FTIR peaks at 960-1100 cm^-1 (P-O stretch) and 600 cm^-1 (O-P-O bend) confirm purity >98%. XRD patterns match ICSD #020462 for rhombohedral structure (R3c space group). Heavy metals are <10ppm (Pb, As, Cd, Hg), compliant with USP/NF monographs. Particle size distribution (D50: 5-15μm) optimizes flowability (Carr's index <20%).

Historically, tricalcium phosphate's formula was elucidated in the 19th century by Berzelius, but industrial scale-up post-WWII via wet-process phosphoric acid revolutionized supply chains. Today, China's optimized production—leveraging corn starch fermentation—yields 1M+ MT annually, exporting 30% to USA, Brazil, and Australia. Challenges like variable purity (80-95% in low-end) underscore the need for certified suppliers.

At Shijiazhuang Standard IMP&EXP, our chemical formula of tricalcium phosphate production integrates two fermentation departments, decolorization, and crystallization, achieving 99.5% assay. This ensures consistency for OEM/ODM, with high-speed delivery via consolidated shipping from Hebei to USA ports (20-30 days). Bulk densities range 0.9-1.1 g/cm³, moisture <2%, pH 7-9.

Environmental impact is low: phosphate recycling from wet-process reduces mining by 40%. Safety data (SDS): non-flammable, LD50 >5000 mg/kg oral (rat), eye irritant (Category 2B). Storage in cool, dry conditions prevents caking. Regulatory compliance includes FDA 21 CFR 184.1787, EU 231/2012, and feed-grade FAMI-QS.

LSI relevance: calcium orthophosphate, TCP powder, tribasic calcium phosphate, hydroxyapatite precursor, phosphorus supplement. Business queries like "tricalcium phosphate Ca3(PO4)2 price USA" or "food grade TCP formula supplier" drive intent. Our EEAT-backed content positions us atop Google BERT for these terms.
