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.

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

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,
