A study of hardness and fourier transform infrared spectra of aluminium oxide

Abstract

Aluminium oxide sample which have been received in pellet form were measured of its hardness by using Affri 206EX hardness testing machine. However, during measurement being read, the sample been broken due to its fragile characteristic. Thus, the reading was taken at about 1.9, which is only 21.11 % from the theory value (9.0). Then, the broken sample from the hardness testing were taken and grinded into powder form to be scanned with Fourier Transform Infrared Spectroscopy (FTIR) and the FTIR spectra analysis have revealed that the strongest peak occurred at 719.265 cm- much probably due to the internal bending of Alz03.
