  2. Hydroxyapatite - Wikipedia

    en.wikipedia.org/wiki/Hydroxyapatite

    The sites occupied solely by phosphate anions in stoichiometric hydroxyapatite, are occupied by phosphate or hydrogen phosphate, HPO 2− 4, anions. [14] These calcium-deficient phases can be prepared by precipitation from a mixture of calcium nitrate and diammonium phosphate with the desired Ca/P ratio, for example, to make a sample with a Ca ...

  3. Calcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Calcium_phosphate

    The term calcium phosphate refers to a family of materials and minerals containing calcium ions (Ca 2+) together with inorganic phosphate anions. Some so-called calcium phosphates contain oxide and hydroxide as well. Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth ...

  4. Tetracalcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Tetracalcium_phosphate

    Tetracalcium phosphate is the compound Ca 4 (PO 4) 2 O, (4CaO·P 2 O 5). It is the most basic of the calcium phosphates, and has a Ca/P ratio of 2, making it the most phosphorus poor phosphate. [1] It is found as the mineral hilgenstockite, which is formed in industrial phosphate rich

  6. Tricalcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Tricalcium_phosphate

    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 ).

  7. Bioglass 45S5 - Wikipedia

    en.wikipedia.org/wiki/Bioglass_45S5

    The 45S5 name signifies glass with 45% by weight of SiO 2 and 5:1 molar ratio of calcium to phosphorus. This high ratio of calcium to phosphorus promotes formation of apatite crystals; calcium and silica ions can act as crystallization nuclei. [5] Lower Ca:P ratios do not bond to bone.

  8. Calcium - Wikipedia

    en.wikipedia.org/wiki/Calcium

    In baking, calcium phosphate is used as a leavening agent. Calcium sulfite is used as a bleach in papermaking and as a disinfectant, calcium silicate is used as a reinforcing agent in rubber, and calcium acetate is a component of liming rosin and is used to make metallic soaps and synthetic resins. [47]

  9. Dicalcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Dicalcium_phosphate

    Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
