Synthesis of microforsterite using derived-amorphous-silica of silica sands
Synthesis of microforsterite (Mg2SiO4) has been successfully done by a simple method
benefiting of the local silica sands from Tanah Laut, Indonesia. The starting material was
amorphous silica powder which was processed using coprecipitation method from the
sands. The silica powder was obtained from a series of stages of the purification process of
the sands, namely magnetic separation, grinding and soa ing with HCl. The microforsterite
synthesis followed the reaction of stoichiometric mole ratio mixing of 1: 2 of the amorphous …
