Colloidal processing of hydroxyapatite

Biomaterials, 2001
Reliable bioceramics are needed to implement the high requirements that living tissues demand. This work focuses on the processing steps necessary to manufacture advanced ceramics that can be used as implant devices. The influence of the heat treatment temperature on the characteristics of a precipitated hydroxyapatite (OHAp) powder was evaluated in ...

Aggregation of hydroxyapatite crystals

Biochimica et Biophysica Acta (BBA) - General Subjects, 1976
A system to study the aggregation of hydroxyapatite crystals was developed. The effect of several factors (Ca2+ x Pi product, Ca2+/Pi ratio, pH, and various substances) were tested. Pb2+, Zn2+, Mg2+ and methyleneblue had only small effects; citrate inhibited aggregation.

Srapping Hydroxyapatite Implants

Ophthalmic Surgery, Lasers and Imaging Retina, 1999
Abstract: Hydroxyapatite (HA) implants currently are most commonly wrapped in fresh unprocessed human donor sclera before implantation to facilitate entry into the orbital space and allow extraocular muscle attachment. Autologous temporalis fascia or autologous fascia lata are alternatives, but prolong surgery time and require a second operative site ...

Hydroxyapatite Chromatography (HAC)

2023
Hydroxyapatite (HA) is a mixed-mode media that has been used extensively for the purification of proteins and DNA since the 1950s. Hydroxyapatite possesses a distinctive selectivity that may be applied in the purification of a wide range of biomolecules: immunoglobulins, alkaline proteins, acidic proteins, and DNA.

Hydroxyapatite–TiO2 composites

Materials Letters, 2006
This article reports the mechanical properties, the microstructure, and the crystallography of composite materials made of hydroxyapatite, obtained from natural bovine bone, and TiO2 (5 and 10 wt.%), which were sintered at different temperatures between 1000 and 1300 °C. Higher sintering temperatures resulted in better densification.
