SINTESIS DAN KARAKTERISASI WOLLASTONIT BERBAHAN DASAR ALAMI DENGAN METODE HIDROTERMAL
ABSTRACT: Indonesia is one of
huge paddy producing countries so that it also produces rice husk in a great number.
Rice husks contain high silica. Which is good in silica compounds synthesis
such as Wollastonit (CaSiO3). Nowadays Wollastonit has attracted great
intension doe to its ability toincrease mechanical properties of a material. In
this work, rice husk was taken from Sariak Laweh, Lima Puluh Kota district and
CaO was taken from Halaban, in the same district. Analysis with XRF show that
SiO2 and CaO content of both samples were high enough, 97%and 98% which
indicated their good potential as silica and calcium source in to synthesize ofWollastonit.
Characterization XRD and SEM were found that the Wollastonit obtained which rice
husks gave good result.
