Kajian Pengaruh Temperatur Sintering terhadap Peningkatan Derajat Kristalinitas Karbon dari Limbah Kulit Kemiri
Allotropes of carbon has advantages in the ability to intercalate ions, atoms or molecules that potentially to apply in various technological applications. Graphite one of allotrope carbon which has well intercalation and ion transport capabilities. In case, the synthesis of activated carbon made from candlenut shell was carried out with carbonization temperatures at 700C and used a chemical activator in form of 30% KOH. After the activation process, given the sintering treatment for activating carbon with temperature of 950C and 1000C, respectively, which this process is expected to increase the crystalline phase of activated carbon close to the graphite phase. The result showed that dominantion of the structures were amorphous, with varying degrees of crystallinity ranging 35.23% and 35.44%, respectively, and the degrees of graphitization 36% and 37% for the vertical and horizontal directions, respectively. The treatment of the sintering process with a temperature of 1000C has the highest degree of crystallinity, 35.44%. This indicates that the sintering process has an effect on the activated carbon
