Fabrication and characterization of porous ceramic panel using recycled glass powder
The porous ceramic panel using glass powder as a main raw material can be applied for the thermal insulator in architecture and industry since it is noncombustible and chemically stable as well as eco-friendly unlike the organic thermal insulators. For the study of fabrication and characterization of this material, we used grinded glass powder with grain size smaller than 150 mu m, and Calcium carbonate(CaCO3) and Calcium phosphate(Ca-3(PO4)(2), CaHPO4 center dot 2H(2)O) as foaming agent. The shape and size of pore cell in porous glass structure with the change of additives and sintering temperature were studied. The physical properties as like density, thermal conductivity and compressive strength of materials are also studied. It was possible to make a porous ceramic panel with multi-layered which has the form of sandwich with layer of low density and high density in one body by adjusting the foaming characteristics.
