cristobalite

Characterization and identification of Maitara Island clay have been carried out. This study aims to determine the types minerals contained in clay. The analytical methods used include X-Ray Fluorescence (XRF) chemical composition clay, Diffraction (XRD) for mineralogical analysis Fourier Transmission Infra Red (FTIR) vibrations that exist between atoms from Island, Scanning Electron Microscopy...

Synthesis of Rice Husk Nanosilica using the Hydrothermal Method

Journal: :IOP conference series 2023

Abstract Synthesis of rice husk nanosilica was carried out using hydrothermal methods at various temperatures and times their characteristics. The stages synthesis include sample preparation, synthesis, reaction temperature variations used are 120°C, 150°C, 180°C, the time is 2 hours, 4 6 hours then titrated sulfuric acid until it reaches pH 7-8. XRF analysis results showed silica (SiO2) conten...
