This paper aims to synthesize high purity nano-sized silica from rice husk ash (RHA) by chemical method and investigate its physical and chemical properties. Through a controlled burning of rice husk, the white-colored RHA is obtained. Next, the RHA is subjected to the pre-treatment of acid leaching...
