Preparation of Inorganic Foam Glass-Ceramic with Utilization of Waste Diatomite as a Raw Material

Abstract

The focus of this research paper is the preparation of inorganic foam glass-ceramic with the utilization of waste diatomite as a raw material. The waste diatomite was first comprehensively characterized by the analysis of the chemical and mineralogical composition, particle size, thermal analyses, and microstructure by scanning electron microscopy. Followed by the pretreatment of the mixtures with the addition of a foaming agent which was sodium hydroxide. The mixtures were then formed by pressing them into pellets and fired by a powder sintering method. The pretreatment drying temperatures and firing temperatures of the prepared mixtures were evaluated. After firing, the resulting properties of the foam glass-ceramic were investigated with the utilization of an X-ray diffraction analysis, bulk density, and compressive strength. The possibility of utilization of waste diatomite in raw material mixtures for the preparation of inorganic foam glass-ceramic was investigated.
