Conductivity of Lanthanum Silicate Apatite Derived from Rice Husk

Abstract:

Effect of difference silica source, namely commersial silica and silica from rice husk, as Si precursor on the synthesis of lanthanum silicate apatite (LSO) have been investigated. The conductivity of LSO was determined by impedance spectroscopy using LCR meter. The conductivity of LSO based on rice husk extraction (s_700°C = 2.13 ´ 10^-4 S.cm^-1) was ten times lower than that of LSO with commercial silica (s_700°C = 3.11´ 10^-5 S.cm^-1). Carbon content as an impurity on silica from rice husk extraction is suspected to decrease the homogeneity of its morphology so that it has an impact on its conductivity.
