“…32 The amount of polyelectrolyte addition also influences the rate of deposition and the homogeneity of the deposited material. 33 Green composite microstructures with good infiltration uniformity and few macro defects have been obtained by this technique, 34,35 and previous work with a SiC f /SiC system resulted in an increase in density from 20 vol.% (the initial fiber preform density) to over 40 vol.% in only 20 minutes. 36 In this work, a methodical examination of the use of stand-alone VB and EPI techniques as well as their combination with a number of geometrical modifications has been undertaken with a view to producing SiC powder-loaded SiC fiber preforms that are suitable for subsequent infiltration with a SiC matrix using CVI.…”

“…The movement of ceramic particles in a suspension within an electric field is governed mainly by factors such as the field strength, the pH of the suspension and its ionic strength . The amount of polyelectrolyte addition also influences the rate of deposition and the homogeneity of the deposited material . Green composite microstructures with good infiltration uniformity and few macro defects have been obtained by this technique, and previous work with a SiC f /SiC system resulted in an increase in density from 20 vol.% (the initial fiber preform density) to over 40 vol.% in only 20 minutes…”

“…O movimento oscilatório destas partículas resulta na transferência de momento para o líquido, gerando uma onda acústica conhecida como efeito ESA (Electrokinetics Sonic Amplitude) [87] . A relação entre a mobilidade eletroforética dinâmica e o sinal acústico medido na suspensão é dada pela seguinte equação [88] :…”
