Continuous precipitation of hydroxyapatite from Ca/citrate/phosphate solutions using microwave heating
TLDR
In this article, the precipitation of hydroxyapatite (HAp) in a continuous process using microwave heating and Ca/citrate/phosphate solutions is presented.Abstract:
The precipitation of hydroxyapatite (HAp) in a continuous process using microwave heating and Ca/citrate/phosphate solutions is presented. Calcium deficient HAp particles in the nanometric size range (<100 nm), with needle-like morphology, were obtained. These chemical and morphological characteristics do not change with the residence time, and are similar to those of HAp obtained in a batch process using also microwave heating and Ca/citrate/phosphate solutions. On the other hand, the steady state is reached faster than in the precipitation of HAp in a MSMPR reactor using non-complexing solutions and conventional heating. In the latter process submicronic (<1 mikrom) needle-like particles are obtained.read more

Monetite Formed in Mixed Solvents of Water and Ethylene Glycol and Its Transformation to Hydroxyapatite
TL;DR: Agglomerated nanorods of hydroxyapatite have been synthesized using monetite as a precursor in a NaOH solution and the effects of the molar ratio of water to EG and the reaction time on the products were investigated.

Morphology and composition of nanograde calcium phosphate needle-like crystals formed by simple hydrothermal treatment
TL;DR: In this article, Nanograde calcium phosphate needle-like crystals are prepared from wet synthesized Ca−P precipitates by simple hydrothermal treatment at 140°C and 0.3 MPa for 2 h. The morphology of these crystals is observed by transmission electron microscopy (TEM).
