Sintesis CaTiO3 Berbasis Limbah Cangkang Telur Bebek Untuk Aplikasi Sel Surya

Abstract

Duck’s eggshell is one type of organic waste that has not been used optimally. Duck eggshell contain CaCO₃ as a CaO source, so they are potentially processed as CaTiO₃. The purpose of this study was to investigate the effect of sintering temperature on morphology, phase, functional groups, and optical properties of CaTiO₃. The sintering temperatures were used in this research from 800^oC, 900^oC and 1000^oC for 4 hours. SEM analysis show that there was the different of morphology properties to each samples. Homogeneity of CaTiO₃ particles can be seen from spherical distribution of CaTiO₃ particles, especially at 800^oC. In this research was found orthorombic crystal structure of CaTiO₃ to each sintering temperatures.According to the XRD patterns, it can be seen that there was a simillar patterns to each samples. Each peaks of CaTiO₃ that formed on 2 (23,329^o; 29,960^o; 33,152^o; 40,990^o; 47,568^o; and 49,211^o) have the growth orientations respectively are (400), (510), (440), (444), (800), and (820). Particle size at sintering temperature of  800^oC, 900^oC and 1000^oC respectively are 43,60438 nm, 33,43218 nm, and 29,35699 nm).
