Wastewater treatment of some heavy metals was carried out by synthetic zeolite P1, which prepared alkaline hydrothermal the pumice. Both pumice raw materials and were investigated for their chemical phase composition, physical properties, microstructure. The adsorption behavior Na-zeolite P1 with respect to Co(+2), Cu(+2), Fe(+2), Cd(+2) has been studied be applied in industrial wastewater treatment. Metal removal using solutions at different ions concentrations, time, Na-P1 doses as well...
The use of solid waste such as ceramic sludge, rollers, and magnesite was studied to obtain cheap refractory ceramics at temperatures 1300 °C based on XRF, XRD SEM, EDX, bending strength, dielectric properties. prepared samples were examined. results showed that the significant crystalline phases formed mullite, spinel, corundum. They also mullite hindered formation cordierite enhanced spinel formation. With increased content, microstructure varied from fine grained coarse grained. Bending...
Abstract The possibility of reusing ceramic roller waste to produce cordierite and mullite refractories was investigated. Five batches were designed using wastes representing waste, magnesite, silica sand, shaped fired at 1300 °C/2 h, one batch selected 1200 °C. chemical composition precipitated phases the used raw materials analyzed XRF XRD techniques, respectively. Densification parameters, morphology, microstructure electrical properties also studied evaluate effect formed on materials....
The aim of the present work is to prepare, characterise and assess MgO–Al2O3–SiO2 refractory ceramics; namely, spinel, mullite cordierite from chemically recycled precipitates. These precipitates include pure fine magnesium aluminium hydroxides as well water treated fumed silica. Corresponding batches aimed oxide ceramics were coprecipitated these subsequently processed up firing using proper techniques. bodies investigated for their chemical phase composition morphology, microstructure...
High alumina refractory batches were prepared from Egyptian clay and imported China calcined bauxite. Three concentrations of phosphoric acid 3, 5, 7%, added to study their effects on some technological properties. Designed tend form a composition 76% ~ 17% silica in addition the other fluxing alkali oxides. Chemical mineralogical as well density plasticity both bauxite was performed. different fired at 1350 °C for 1 h. Densification parameters cold crushing strength thermal shock resistance...
Egyptian Upper Cretaceous waste clay samples from Yunis Mines, Qusseir vicinity, Eastern Desert, were investigated for their chemical and mineralogical compositions as well firing. These investigations carried out to assess the suitability use clays production of lightweight bricks. X-ray fluorescence (XRF), scanning electron microscopy (SEM), diffraction (XRD), Fourier transform infrared (FTIR) techniques applied characterizing mineral raw clays. On other side, densification parameters...
Abstract Background The present title is aiming to study the effects of trachyte additions on sinterability ceramic tiles. Four batches were designed with different trachyte/clay ratios from 10 40% and 3% bentonite. Results Chemical phase composition raw materials investigated using XRF XRD techniques as well petrographic examination. prepared fired 1140 1280 °C, their densification parameters compositions microstructure investigated. Petrographically, studied trachytic rocks are fine medium...
Granitic weathering products were obtained from South Sinai.These aggregates assessed to be used in the manufacturing of cement concrete.Chemical and mineralogical compositions physical parameters selected samples carried out.The composition main phase is quartz, albite, microcline, while river sand shows only quartz as one phase.Four batches designed with two different grain size divisions between fines medium granules.Two granite for all sizes.The other coarse a fine sand.Some...
