Tricalcium phosphate (sometimes abbreviated TCP), more commonly known as Calcium phosphate, is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2. It is also known as tribasic calcium phosphate and bone phosphate of lime ( BPL ).
The tricalcium phosphate in bone char can be used to remove fluoride [3] and metal ions from water, making it useful for the treatment of drinking supplies. Bone charcoal is the oldest known water defluoridation agent and was widely used in the United States from the 1940s through to the 1960s. [4]
Calcium phosphate-based ceramics constitute, at present, the preferred bone substitute material in orthopaedic and maxillofacial applications, as they are similar to the main mineral phase of bone in structure and chemical composition. Such synthetic bone substitute or scaffold materials are typically porous, which provides an increased surface ...
Calcium phosphate stones account for approximately 15% of kidney stone disease. Calcium phosphate stones tend to grow in alkaline urine, especially when Proteus bacteria are present. It is the most common type in pregnant women. [6] Calcium phosphate is the usual constitution of microcalcifications of the breast, particularly dystrophic ...
Wet-process phosphoric acid is prepared by adding sulfuric acid (H 2 SO 4) to apatite or tricalcium phosphate rock resulting in the following reaction: 3 H 2 SO 4 + Ca 3 (PO 4) 2 + 6 H 2 O ↔ 2 H 3 PO 4 + 3 CaSO 4 •2H 2 O Wet-process acid has to be purified by removing fluorine and other undesirable elements to produce feed-grade phosphoric ...
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Amorphous calcium phosphate (ACP) is a glassy solid that is formed from the chemical decomposition of a mixture of dissolved phosphate and calcium salts (e.g. (NH 4) 2 HPO 4 + Ca(NO 3) 2). The resulting amorphous mixture consists mostly of calcium and phosphate, but also contains varying amounts of water and hydrogen and hydroxide ions ...
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.
