calcium phosphate

[′kal·se·əm ′fäs‚fāt]
(inorganic chemistry)
Any phosphate of calcium.
Any of the following three calcium orthophosphates, all of which are white or colorless in pure form: Ca(H2PO4)2 is used as a fertilizer, as a plastics stabilizer, and in baking powder, and is also known as acid calcium phosphate, calcium dihydrogen phosphate, monobasic calcium phosphate, monocalcium phosphate; CaHPO4 is used in pharmaceuticals, animal feeds, and toothpastes, and is also known as calcium hydrogen phosphate, dibasic calcium phosphate, dicalcium orthophosphate, dicalcium phosphate; Ca3(PO4)2 is used as a fertilizer, and is also known as tribasic calcium phosphate, tricalcium phosphate.

Through a separate medial incision under sterile technique, this area was injected with 5 cc of calcium phosphate cement.
Calcium phosphates such as hydroxyapatite and tricalcium phosphate can be readily fabricated synthetically in the laboratory from different reactions, there are different routes for synthesis instead of using minerals present in nature, the most prominent are the solid-state synthesis, wet or dry method, hydrothermal method, solgel methods, thermal processing in the case of tricalcium phosphate pass from a to P in two ways.
Calcium phosphate cement (CPC) possesses excellent biocompatibility and osteoconductivity in vivo and is commonly used as a biomaterial in bone implants [1].
Being similar to the major inorganic component of natural bone, the inorganic compound such as hydroxyapatite (HAp) or a calcium phosphate in a composite scaffold provides good osteoconductivity while the polymer provides the continuous structure and design flexibility to achieve the high porosity and high surface area, which are necessary for anchorage-dependent cells such as osteoblasts to survive and differentiate [1].
This review provides an overview of the current state of BTE with a focus on bone morphogenetic proteins (BMPs), calcium phosphate (CaP) scaffolds, and mesenchymal stem cells (MSCs).

In composite bioceramics world, many researchers have focused their interest on the development of biphasic calcium phosphate (BCP) ceramics, especially with hydroxyapatite (HA: [Ca.sub.10][(P[O.sub.4]).sub.6][(OH).sub.2]) and tricalcium phosphate (TCP: [Ca.sub.3][(P[O.sub.4]).sub.2]).

Chemically modified calcium phosphates as novel materials for bisphosphonate delivery.
When applied to dissolution of calcium phosphate materials, this technique is based on the principle that dissolution of most calcium phosphates, such as HA, consumes protons ([H.sup.+] ion).
