General description

Hydroxyapatite Coating Powder consists of rounded particles obtained by spray drying. This pure and 100% synthetic HA material has been specially developed for plasma coating purposes. The specific morphology and particle size distribution enables good flowability of the powder and enables us to manufacture smooth-finished and highly adhesive coatings.

Application

Suggested use for manufacturing of inks for additive manufacturing, composite materials, and CaP based putties.

Storage Class Code

11 - Combustible Solids

A systematic characterisation of bone tissue scaffolds fabricated via 3D printing from hydroxyapatite (HA) and poly(vinyl)alcohol (PVOH) composite powders is presented. Flowability of HA:PVOH precursor materials was observed to affect mechanical stability, microstructure and porosity of 3D printed scaffolds. Anisotropic

In this work we have investigated the effects of strontium (Sr) dopant on in vitro protein release kinetics and in vivo osteogenic properties of plasma sprayed hydroxyapatite (HA) coatings, along with their dissolution behavior. Plasma sprayed HA coatings are widely

The ideal bone tissue engineering scaffolds are long-cherished with the properties of interconnected macroporous structures, adjustable degradation and excellent biocompatibility. Here, a series of porous α/β-tricalcium phosphate (α/β-TCP) biphasic bioceramics with different phase ratios of α-TCP and β-TCP were successfully
