Although mullite–zirconia composites made from zircon, alumina, and andalusite meet the requirements for many refractory applications, little effort has been to transfer these bonding phase (the ‘matrix’) of bricks. In this paper, we investigate how could be achieved through better control secondary oxides. The high temperature phases were simulated with thermodynamic software linked microstruc...

The mineralogical investigation, geochemical analysis, and grain size calculation were carried out for floodplain sediment in the Tigris River to identify properties of sediment. average values three main classes, very fine sand, silt, clay are 9.67, 62.53 27.80%, respectively. silt fraction was predominant. classification nomenclature surface types from sandy-silt mud, they dominant Statistica...

Mineral assemblages, reaction textures and mineral composition of the metapelitic rocks from the Mahneshan area in NW Iran are studied to reconstruct the reaction history of the rocks. The phase relation on the real mineral chemistry AFM, AFMn compatibility diagrams and mineral isograds in chloritoid-free and chloritoid-bearing metapelites of Mahneshan Complex were studied in order to determine...

Adsorption of lead(II) as a major heavy metal pollutant onto nano-adsorbents of Andalusite, Kyanite and Sillimanite was studied in a batch system. Nano­-adsorbents were prepared via crushing, using a planetary ball mill and then characterized by different analyses such as: SEM, XRD, XRF and FT-IR. Major factors affecting the adsorption process were studied including pH, adsorbents dosage, initi...
