| Summary: | 碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 86 === Using the physical method to simplify montmorillonite can separate the differe
nt crystalline minerals ; but can't to leave the ionic impurity . The reserach
adopts the electrochemical way to simplify montmorillonite further . When the
potential equals to -0.8V , that Ti4+will be reducted from the site of the oc
tahedral bonding . Using the Rietveld method to analyse the crystal of montmor
illonite , and discovering that the distorted bonding will restore comply with
removing the titanium . Judging the suitabi Montmorillonite is the littles
t particle in the clay minerals , its size always be small than 3um , which i
s called nanoparticle . It is very important to control the particle's dispers
ing and condensing in a aqueous . The study is to find the precipitate quantit
y of surfactant PVA , correlated to the rest potential and its particle size d
istribution . It wants to use the potential to control the particle size . It
discovers that using PVA/Mont.=12wt% in 0.5wt% montmorillonite solution , wil
l makes mo In the other way , finging sericite's particle size , simultaneo
usly.
