Abstract
Recent research on Hausmannite is becoming more interesting to be examined because of its advantages that can be used in a variety of applications. The purpose of this research is to investigate the influence of temperature variation of calcination on thin film structure of Hausmannite. This type of research is an experimental research. The Hausmannite used was derived from manganese ore which had been sintered for 3 hours at a temperature of 1000 °C and milling for 8 hours. This sample is made in the form of a thin layer with Sol-Gel Spin Coating method. In this research, the variation of calcination temperature is 200 °C, 300 °C, 400 °C and 500 °C . Then to analyze the structure of thin film Hausmannite formed used X-ray difraction. Based on characterization results using X-ray difraction. The thin layer formed based on the result of X-ray difraction is Mn3O4 and Mn2O3. As for the variation of calcination temperature, the difference of intensity of the diffraction peaks formed then the crystal size for each calcination temperature 200 °C, 300 °C, 400 °C and 500 °C were 41.06 nm, 52.37 nm, 47.73 and 47.87 nm
