Caracterização estrutural e elétrica de óxidos semicondutores do tipo espinélio.
(Universidade Federal de São Carlos, 2002-10-14)
Desenvolvimento de um equipamento para avaliar propriedades elásticas de cerâmicas refratárias a altas temperaturas pelo método de ressonância de barras.
(Universidade Federal de São Carlos, 2002-09-12)
The knowledge of the elastic properties has been of fundamental
importance for the understanding of the limitation of the useful life of structural
refractory ceramics. Those properties characterize the elastic rigidity ...

(Universidade Federal de São Carlos, 2002-02-19)
The fast growing of regional jets market has required from airframe manufacturers a prompt attending to market demands and the primary parts fabrication at a planned quality, quantity, and time at low costs. In order to ...
Caracterização de sistemas varistores a base de SnO2-MnO2.
(Universidade Federal de São Carlos, 2002-08-02)
This work focussed on the effect of addition of Nb2O5 on the electrical and microestructural properties of SnO2-MnO2 based ceramics. It was also studied the effect of heat-treatments in a oxygen-rich atmosphere in these ...
Processamento de pós ultrafinos e nanométricos por moagem de alta energia para a obtenção de compósitos cerâmicos Al2O3-(5%vol.)TIC.
(Universidade Federal de São Carlos, 2002-09-13)
The major objective of this thesis was to study the processing behaviour of Al2O3 ultra-fine and nanosized powders obtained by high energy milling
(HEM), to produce, after forming and sintering, Al2O3 .(5%vol.)SiC and Al2O3 ...
