α-Tricalcium phosphate: Synthesis, properties and biomedical applications
TLDR
It is as biocompatible as β-TCP, but more soluble, and hydrolyses rapidly to calcium-deficient hydroxyapatite, which makes α- TCP a useful component for preparing self-setting osteotransductive bone cements and biodegradable bioceramics and composites for bone repairing.About:

Ana Cláudia de Souza,Craig McNulty,José Ângelo Camilli,Celso Aparecido Bertran,Mariana Motisuke +4 more
TL;DR: The biomaterial evaluated was shown to be non-cytotoxic, resorbable, and capable of inducing bone neoformation; however, more studies should be carried out to assess the application of this biomaterial in bone injuries.
Synthesis of calcium phosphates from abalone shells via precipitation
Sung Wook Moon,Byeong Woo Lee +1 more
Abstract: Calcium phosphates recognized as important bio-materials have been successfully synthesized by simple precipitation using waste abalone shells, which are rich mineral sources of calcium. Calcium hydroxide (Ca(OH)2) originated from abalone shells was used as calcium source (precursor) for the preparation. Synthesis of calcium phosphates was performed by reacting calcium hydroxide with phosphoric acid (H3PO4) in aqueous solution. The initial precursor Ca/P ratios were adjusted to 1.50, 1.59 and 1.67, and the effect of the composition and the heat treatment on the synthesized powders and sintered bodies was investigated. The phases of the sintered ceramics prepared at 1150 o C were hydroxyapatite (HAp), -tricalcium phosphate (-TCP), and biphasic phosphate (HAp with -TCP)), which were determined by the initial precursor Ca/P ratios. The results demonstrate the possibility for the synthesis of high value-added calcium phosphates from economical starting materials with low cost and high availability.

Comparative Study of in-vitro Behavior of Tetracalcium Phosphate-based Cement: Ringer's Solution versus Human Blood Plasma
TL;DR: In this article, the apatite-forming ability of calcium phosphate cement (CPC) was evaluated in two different media; human blood plasma and Ringer’s solution, and the results showed that the APatite formation ability of an implant in a supersaturated solution has been widely used to investigate its bioactivity.
