Abstract: (1456 Views)
Zircon refractory patching materials are products containing zircon, kaolin and phosphate binders that applied with trowelling method for partial repairing in the glass melting tanks. Therefore the studying of their properties has the special importance from point of view of industrial applications and phosphate binders phase evolutions. In this research project, after selecting different formulations containing zircon with various PSD, s and adding different amounts of kaolin, P2O5 containing chemicals and water, some samples were prepared.
P2O5 containing chemicals were sodium hexameta phosphate (HMP), sodium tripoly phosphate (TPP), Sodium aluminum dihidrogen phosphate and phosphoric acid. After preparing the samples and drying and sintering between 500-1400°C, physical and mechanical properties according to ASTM standards were measured. The results showed that using of TPP binder has the proper performance from points of view of mechanical properties. Also the samples containing 7-10% wt kaolin and 3-5% wt P2O5 had the best properties than the others. Finally some samples were selected for microstructural and phase studies with scanning electron microscopy (SEM+EDS) and X-ray diffraction (XRD) techniques.
