Formation of octacalcium phosphate in the interaction of calcium carbonate and monocalcium phosphate monohydrate under galvanostatic conditions
نویسندگان
چکیده
The calcium phosphate composite octacalcium / calcite was obtained at pH 5–7 from the CaCO 3 /Ca(H 2 PO 4 ) aqueous suspension in a galvanostatic mode current density of 20 mA/cm for min. Drying 80 °C without precipitate maturation stage led to powder formation consisting brushite, and small amount phosphate. Prolonged air months hydrolytic transformation brushite into stabilized by calcite. use electric made it possible increase with morphology lamellar rosettes. Calcination 800 powders α/β-tricalcium phosphate, β-calcium pyrophosphate, hydroxyapatite, oxide.

Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...

ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...
متن کاملCalcium Acetate Versus Calcium Carbonate as Oral Phosphate Binder: Preparation and In Vitro Assessment
Calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. Compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. In this study, various formulations of calcium acetate tablets were prepared and their disint...
