Isomorphic Substitution in Vanadinite [Pb5(VO4)3C1] - Raman Spectroscopic Study [PDF]

, 2003
The Raman and infrared spectroscopy of three vanadinite [Pb5(VO4)Cl] specimens from three localities has been studied. Single crystal Raman spectra were obtained and the spectra were found to be both orientation and temperature dependent.

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

, 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.

Recent research progress of luminescent materials with apatite structure: A review

Open Ceramics, 2022
Phosphors with apatite structure have shown potential applications in solid-state lighting and display industry due to their flexible crystal structure, controllable chemical composition and different crystallographic positions of single doped or co ...

Progress on the preparation of nanocrystalline apatites and surface characterization: Overview of fundamental and applied aspects [PDF]

, 2013
Nanocrystalline calcium phosphate apatites constitute the main inorganic part of hard tissues, and a growing focus is devoted to prepare synthetic analogs, so-called “biomimetic”, able to precisely mimic the morphological and physico-chemical features of

Safe-by-Design Antibacterial Peroxide-Substituted Biomimetic Apatites: Proof of Concept in Tropical Dentistry

Journal of Functional Biomaterials, 2022
Bone infections are a key health challenge with dramatic consequences for affected patients. In dentistry, periodontitis is a medically compromised condition for efficient dental care and bone grafting, the success of which depends on whether the ...

Apatite Formation on Titanium Containing Apatite

Bioceramics Development and Applications, 2013
Some titanium containing apatite (TMA) ceramics prepared by wet synthesis was superior to Hydroxyapatite (HAp) ceramics of mechanical property and cutting performance. In this study, we investigated chemical reaction of TMA in a body environment. Each TMA or commercial Hydroxyapatite powder (HAp) was formed to circular pellets by uniaxial pressing. The

Apatite Biominerals [PDF]

Minerals, 2016
Calcium phosphate apatites offer outstanding biological adaptability that can be attributed to their specific physico-chemical and structural properties. The aim of this review is to summarize and discuss the specific characteristics of calcium phosphate apatite biominerals in vertebrate hard tissues (bone, dentine and enamel). Firstly, the structural,

Comparison of fluoridated apatites with pure hydroxyapatite as potential biomimetic alternatives to enamel for laboratory-based bond strength studies

Australasian Orthodontic Journal, 2023
To investigate whether fluoridated apatites have a shear bond strength which more closely equates to that of natural enamel than pure hydroxyapatite, making them potentially useful as biomimetic alternatives to natural enamel for ex vivo laboratory ...

Nanocrystalline apatites: From powders to biomaterials [PDF]

, 2009
Non-stoichiometric nanocrystalline apatite powders are used to elaborate highly-bioactive biomaterials. Their exceptional surface reactivity arises from a structured but rather unstable hydrated layer involving ions in nonapatitic chemical environments ...
