High strength and thermal shock resistant mullite-bonded porous SiC ceramics are essential for applications in catalyst, hot gas/solid filtration/separation fields. However, these properties were limited by the contradictory issue: higher temperature is necessary formation densification of mullite bond phase, while lower preferred to avoid sever oxidation accompanied with detrimental cristobali...

Abstract Kaolin is widespread as a result of the alteration in San José Sn-Ag deposit located Oruro, Bolivia. This study presents chemical, mineralogical and thermal characterization kaolinitic deposit, which necessary to determine their optimal applications. Mineral phases these white silty materials were determined by X-ray diffraction (XRD) are quartz, kaolinite, K-feldspar, muscovite, illit...

Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...

The effect of monoaluminum phosphate (Al(H2PO4)3) addition in the thermochemical process a kaolinitic clay was studied and compared with pure clay. Monoaluminum incorporation is technological interest for widely use this material as an effective binder. From point view important to clarify processing strategy clay-MAP based ceramics. This work comprised characteristics obtained ceramics using d...
