betatricalcium
Betatricalcium is not a widely recognized or unambiguous term in standard chemical literature. In the absence of a precise definition, the expression often invites interpretation from related calcium-containing compounds. The most plausible reading is a reference to a beta polymorph of a calcium phosphate compound containing three calcium atoms, most commonly beta-tricalcium phosphate (β-TCP, Ca3(PO4)2). Another possibility is that the term is a shorthand or misnomer for a beta-phase calcium silicate or other beta-phase calcium salts discussed in specific technical contexts. Because of the lack of a settled definition, any use of the term should be accompanied by context or a chemical formula.
Beta-tricalcium phosphate (β-TCP) is the best-supported interpretation in practical terms. β-TCP is a calcium phosphate ceramic
If betatricalcium appears in literature outside biomaterials, it may refer to a different beta-phase calcium compound
