Abstract:
The aim of this work is to identify the chemical, mineralogical and physical properties of quartzites from the Kaélé deposit, in order to identify their potential applications. To achieve this, characterization methods such as X-ray fluorescence spectrometry and X-ray diffraction, Fourier transform infrared spectroscopy (FTIR) and a furnace for melting temperature determination were deployed. The chemical composition of the quartzites determined by X-ray fluorescence spectrometry revealed that silicon oxide (SiO2) is the majority constituent, with a mass percentage of 99.02%. The X-ray diffraction spectrum shows only quartz as the mineralogical phase present in quartzites. Quartzites have an average melting point of 1725°C, which is close to the theoretical value and makes the materials studied pure bodies. The various results obtained highlight the high purity of the quartzites from Kaélé. High-purity quartz has numerous applications in high-tech industries. The main ones are semiconductors, high-temperature lamp tubes, telecommunications and optics, microelectronics and photovoltaic cells. Kaélé quartzites can therefore be considered as highly valuable local mineral materials in the above-mentioned fields.
