Spark plasma extrusion of binder free hydroxyapatite powder

Nanotechnology Reviews, 2022
This work explores the possibility of manufacturing dense and nanocrystalline hydroxyapatite (HA) large monoliths by spark plasma extrusion (SPE). This method combines uniaxial mechanical compression, high temperature, and electromagnetic field to ...

Mechanical property of pixel extrusion and pin forming for polymer, ceramic, and metal formation

Heliyon, 2023
The rapid material fabrications in pixel shape were mechanically studied in comparison with FDM and STL 3D printing technique. The pixel extrusion technique was the extrusion with a set of holes in the die. By controlling the flow of each hole in the die,

Recent Developments in Mechanochemical Materials Synthesis by Extrusion

Advanced Materials, 2016
Mechanochemical synthesis, i.e., reactions conducted by grinding solid reactants together with no or minimal solvent, has been demonstrated as an excellent technique for the formation of both organic and inorganic compounds. Mechanochemistry is viewed as an alternative approach to chemical synthesis and is not always considered when developing ...
