Conductive copper paste is a promising material for use in electronic devices, replacing silver or other metal pastes, because of its high conductivity, low electro-migration, and cost. However, the high sintering temperature and the need of an inert sintering atmosphere limit the commercial application of copper paste. In this study, a copper thic...
The use of microwave heating to produce ceramics is an interesting way to obtain a faster densification compared to conventional heating. The objective of this thesis is to study, experimentally and numerically, the microwave sintering of alumina (Al2O3) in a 2.45 GHz single mode cavity in a hybrid configuration. For this purpose, silicon carbide (...

Blockage of the off-gas duct by dust contained in raw off-gas extracted from a submerged arc furnace (SAF), has been a recurring problem at a South African silicomanganese (SiMn) producer. The problem experienced has prompted an investigation in which sintering of the dust is evaluated as a possible mechanism for the observed blockages. As sinterin...

This article describes the manufacturing of silicon carbide composites with the addition of quasi-two-dimensional titanium carbide Ti3C2, known as MXene. The composites were obtained by the powder metallurgy technique, consolidated with the use of the Spark Plasma Sintering method at 1900 °C and dwelled for 30 min. The influence of the Ti3C2 MXene ...

Lead-free Na0.5K0.44Li0.06NbO3 + xWO3 (x = 0–0.08) piezoelectric ceramics were prepared by the conventional solid-state sintering technique. The effect of WO3 content on the crystal structure, piezoelectric properties, and temperature stability was investigated. X-ray diffraction and Raman analysis showed that all the Na0.5K0.44Li0.06NbO3 + x WO3 c...

In this study, powder metallurgy was applied in a furnace atmosphere to form titanium boride layers on a commercially pure Ti surface. Experiments were carried out using the solid-state boriding method at 900 °C and 1000°C for 12 h and 24 h. Samples were produced by pressing the commercially pure Ti powders under 870 MPa. The sintering process requ...
In this work, Graphene NanoPlatelets (GNP)/Aluminum (Al) composites reinforced from 0 wt% to 2.0 wt% GNP were studied. All different composition powders were stirred for 2 h at a speed of 35 rpm in a V-type mixer to obtain a homogeneous dispersion. Then the compositions were synthesized by ultra-high frequency induction heated sintering (UHFIHS) at...
