Synthesis and Characterization of Calcium Silicate from Rice Husk Ash and Shell of Snail Pomacea Canaliculata by Solid State Reaction

摘要

Calcium silicate was successfully synthesized using agricultural byproduct such as rice husk ash and shell of snail namely Pomacea canaliculata by solid state reaction. Chemical composition of silica in rice husk ash and calcium oxide in shell were 91.50 and 98.25%, respectively by X-ray fluorescent determination. The rice husk ash and shell in molar ratio of 1:1 were milled for 5-8 hr and calcined at 800-1000°C for 2 hr. The Fourier transforms infrared spectra and X-ray diffractometry pattern were confirmed the formation of calcium silicate as the milling time increased.
