APATITES FORMATION ON ELECTRODEPOSITED CALCIUM PHOSPHATES IN THE Ca(NO3)2 / NH4H2PO4 AND CаCO3 / Ca(H2PO4)2 SYSTEMS

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021
Calcium phosphate coatings on titanium plates were obtained by electrochemical deposition at room temperature in a two-electrode cell at a constant current density of 30 mA/sm^2 and a deposition time of 10 min, and brushite coatings from Ca(NO3)2 ...

Nanoparticulate hydroxyapatite and calcium-based CO2 sorbents [PDF]

open access: yes, 2012
This thesis is focused on the development of synthesis and characterisation protocols for two different nanoparticulate materials; hydroxyapatite (HA), a biomaterial well recognised as chemically akin to human bone, and CaO, a material often used for the

Amorphous calcium phosphates: synthesis, properties and uses in biomaterials [PDF]

open access: yes, 2010
This review paper on amorphous calcium phosphates (ACPs) provides an update on several aspects of these compounds which have led to many studies and some controversy since the 1970s, particularly because of the lack of irrefutable proof of the occurrence

Calcium carbonate-calcium phosphate mixed cement compositions for bone reconstruction [PDF]

open access: yes, 2006
The feasibility of making calcium carbonate-calcium phosphate (CaCO3-CaP) mixed cements, comprising at least 40 % (w/w) CaCO3 in the dry powder ingredients, has been demonstrated.

Electrosprayed calcium phosphate coatings for biomedical purposes [PDF]

open access: yesBIOmaterialien, 2007
The suitability of the electrostatic spray deposition (ESD) technique was studied for biomedical purposes—i.e., deposition of calcium phosphate (CaP) coatings onto titanium substrates. Using ESD, which is a simple, inexpensive deposition method for inorganic and organic coatings, it was possible to obtain thin CaP layers with an extremely wide range of

A thermochemical approach for calcium phosphate precipitation modeling in a pellet reactor [PDF]

open access: yes, 2003
A common pathway for P-recovery from wastewater is phosphate precipitation as calcium phosphates. In this paper, a thermodynamic model for phosphate precipitation is proposed based on various models of activity coefficients taking into account various ...
