Popis:	Mount Sinabung volcanic ash is a basic material that can be used to produce silicon dioxide (SiO 2). SiO 2 can be used as a building raw material as well as in food and beverage packaging. To produce SiO 2, the volcanic ash of Mount Sinabung must be synthesized using the coprecipitation method. The result of this process produces SiO 2 content as much as 48%, a formed function group that states the existence of SiO 2 namely Si-O-Si and Si-O at absorption of 1095.57 cm-1 and 798.53 cm-1. From the results of SEM can be seen the morphology of SiO 2 formed. In the XRD results, the phase of SiO 2 is amorphous.
