Frequently Asked Questions

What is tricalcium phosphate used for?

Tricalcium phosphate (Ca3(PO4)2, CAS 7758-87-4) is an inorganic calcium phosphate used in fertilizers and animal-feed supplements, as an anticaking and free-flow agent in powders, as a raw material for glass and ceramics, in polishing and dental powders, and as a stabilizer in plastics. We supply it as a powder in bulk.

Is tricalcium phosphate water soluble?

No. Tricalcium phosphate is practically insoluble in water (though soluble in dilute acids), which is why it works well as an anticaking and free-flow agent in dry powdered products. Solubility and particle-size data for a lot are on the technical data sheet.

What is the chemical formula of tricalcium phosphate?

Tricalcium phosphate has the formula Ca3(PO4)2 (also written Ca3O8P2), CAS 7758-87-4. Full identity and purity specifications are provided on the Certificate of Analysis with each lot.

What is the HS code for tricalcium phosphate?

Tricalcium phosphate classifies under HS 2835.26 (other phosphates of calcium). Confirm the destination-country tariff line with your customs broker. We supply commercial and shipping documentation to support clearance.

What is the price of bulk tricalcium phosphate and how is it packaged?

Pricing is quote-based and depends on grade (e.g., technical, feed), volume, and packaging (bags, supersacks). Request a bulk quote with your target volume and intended application for current pricing, CoA, and SDS.
