Sinterabilidade, desenvolvimento microestrutural e caracterização elétrica do BaCe0,9Y0,1O3-ẟ nanométrico obtido por mistura de óxidos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-11-28)
In this thesis, we investigated the microstructural development of BaCe0,9Y0,1O3-ẟ starting from aggregate-free submicrometric and nanometric powders. The differential of these powders is that synthesis occurred via ...
SUPERCONDUCTING WIRES OF CU-NB3SN - THE LIQUID-PHASE SINTERING METHOD

Fundamental aspects of sintering of chromites concentrates
(London, 2014)
Brazilian chromite ores need to be crushed to a size below 1 mm to allow concentrations that decrease the content of gangues. The concentrate particle size distributions therefore are not favourable for sintering. The ...
Effect of pH-induced nanopowder deagglomeration on sintering, microstructure and dielectric properties of Ba0.77Ca0.23TiO3 ceramics
(ABM, ABC, ABPol, 2012)
Ba0.77Ca0.23TiO3 ceramics were produced in this work starting from nanopowders synthesized via a polymeric precursor method. By adjusting the pH values of the precursor solutions above 7, it was possible to prepare powders ...
Estudo da preparação e sinterização do composto de W-Cu a partir de pós iniciais de W e CuO
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2018-06-29)
In this work, the steps of preparation and sintering of the W-Cu compound from W and CuO powders were studied. For this purpose, high energy milling (HEM) was used to produce composite powders with refined and homogeneous ...
