Alpha-tricalcium phosphate is a high-temperature polymorph of TCP. Due to its reactivity it easily hydrolyzes to calcium deficient hydroxyapatite (CDHA), the main crystal phase of the mineral component of bone. Using standardized production processes, INNOTERE offers alpha-TCP powders with high phase purity and batch-to-batch reproducibility.
