A moldagem por injeção em baixa pressão (MIBP) tem constituído, nos últimos anos, uma excelente alternativa para a produção de pequenos lotes de peças cerâmicas diversificadas e com formas complexas. Esta técnica de conformação é relativ

In this paper the influence of pressure and temperature on four compounds with defect pyrochlore structure (NH4NbWO6, RbNbWO6, CsNbWO6 and p-WO3) is explored by means of X-ray diffraction, vibrational (Raman and infrared absorption) spectroscopy and

An innovative route to promote adhesion between CVD diamond and WC-Co substrate, based on a high-pressure and high-temperature processing, is presented. It was investigated the brazing of the film on the substrate using a AgCu–Ti (5 wt.%) filler an

In this work we investigated the use of partially stabilized zirconia (PSZ) as the substrate for deposition of CVD diamond films. The polycrystalline PSZ substrates were sintered at high temperatures and the results showed that this material has uniq

Boron carbide-based ceramics were obtained by pressureless sintering at 2250 °C in the presence of several additives (C, B, TiB2 and SiC). All the samples were prepared under the same conditions, thus improving uniformity and comparability for metho

It has been shown that zirconium tungstate (ZrW2O8) exhibits isotropic negative thermal expansion and undergoes pressure-induced amorphization above 1.5 GPa, at room temperature. Now, we have found that amorphous ZrW2O8 undergoes endothermic recrysta

The thermoelectric materials CoSb 3 and LaFe 3 CoSb 12 with skutterudite structure were subjected to high pressures using a diamond anvil high-pressure cell up to 20 GPa. Energy-dispersive X-ray diffraction was used to determine the dependence of the
