Spark plasma sintering of hydroxyapatite powders

Biomaterials, 2002
Dense hydroxyapatite (HA) compacts have been successfully fabricated by a spark plasma sintering (SPS). The sintering behavior of HA powders at different temperatures ranging from 850 degrees C to 1100 degrees C was studied. Results showed that spark plasma sintering resulted in rapid densification to near theoretical density.

Spark Plasma Sintering of Nano-Crystalline Ceramics

Key Engineering Materials, 2004
Spark Plasma Sintering (SPS) has been successfully applied in the sintering of nanocrystalline BaTiO3 and gamma-Al2O3 in order to reach fully dense nanostructured ceramics at moderate pressure and temperature. BaTiO3 compacts with densities exceeding 97% and gain size of 50 nm have thus been prepared at temperatures not exceeding 850degreesC using a ...

Spark plasma sintering of ultra refractory compounds

Journal of Materials Science, 2008
Spark plasma sintering experiments were conducted on Zr- and Hf- based borides and carbides with addition of 1, 3, and 9 Vol% MoSi2 as sintering aid. For comparison, as-received ZrC, HfC, ZrB2, HfB2 powders were also sintered. The microstructural features were investigated by means of SEM-EDS technique.

Carbon Contamination Prevention during Spark Plasma Sintering

ACS Applied Materials & Interfaces, 2023
Carbon contamination from graphite molds during spark plasma sintering (SPS) considerably affects the properties of the sintered materials, especially transparent ceramics. Herein, transparent Y3Al5O12 (YAG) ceramics were prepared via SPS using Mo and Ta foils, separately and in tandem, as protective barriers against carbon contamination.

Spark Plasma Sintering of Alumina

Journal of the American Ceramic Society, 2002
A systematic study of various spark plasma sintering (SPS) parameters, namely temperature, holding time, heating rate, pressure, and pulse sequence, was conducted to investigate their effect on the densification, grain‐growth kinetics, hardness, and fracture toughness of a commercially available submicrometer‐sized Al

Spark plasma sintering of BiFeO3

Materials Research Bulletin, 2009
Dense BiFeO3 ceramics were prepared by a novel spark plasma sintering (SPS) technique. The sintering was conducted at temperatures ranging from 675 to 750 8C under 70 MPa pressure. A bulk density value up to 96% of theoretical density was achieved in the process.

Characterization of spark plasma sintered Ag nanopowders

Nanotechnology, 2010
The low temperature sintering behaviour of nanocrystalline Ag powder (with an average size of 70 nm) was characterized. Using spark plasma sintering (SPS), the Ag nanopowders can be successfully sintered at low pressure for only 5 min without external heating, and the sintering density increases and porosity decreases significantly with increase in the

Nanostructured CoSi Obtained by Spark Plasma Sintering

Journal of Electronic Materials, 2015
Cobalt monosilicide is a cheap, environmentally friendly thermoelectric material for medium temperatures (200–700°C). While its power factor is similar to the state-of-the-art thermoelectric materials, its thermal conductivity is too large to reach high ZT values.
