Kajian Pengaruh pH dan Konsentrasi Logam Pada Pembuatan Anoda Berdimensi Stabil Gafit/La2O3-ZrO2 dan Gafit/RuO2-TiO2
ABSTRACT: The objective of
this research is to study the effect of pH and metal concentration toward the mass
of metal oxides coated on gaphite in the synthesis of dimensionally stable
anode (DSA) gaphite/La2O3-ZrO2 and gaphite/RuO2-TiO2. The synthesis of
those DSA was done by thermal
decomposition technique. The solution containing metal ion to be coated (as its
oxides) on the gaphite, followed by heating. Those spraying and heating were
repeated up to ten times, so that it was expected that all of gaphite surface
was covered by the metal oxides. It was concluded that the mass of metal oxides
coated on the gaphite was affected by the pH and concentration of metals in the
solutian to be sprayed. Treatment by using solution at pH of 4 and 6
produced more in mass of metal oxides
mixture than using solution of 1 and 2
on pHs. DSA gaphite/La2O3-ZrO2 produced by treatment using solution of 4 and 6
on pHs contained more in mass of La2O3 than of ZrO2; meanwhile DSA
gaphite/RuO2-TiO2 produced in this research (for all of treatment) contained
more in mass of RuO2 than of TiO2.
