Abstract In this work the synthesis of hercynite from Fe 2 O 3 and Al powders was carried out by arc-melting method under protective argon atmosphere. The obtained material characterized with use powder X-ray diffractometry (XRD) Mössbauer spectroscopy (MS). A effect in indicated cations distribution spinel structure among tetrahedral octahedral interstices. presence 2+ ions detected both sites while 3+ occupied only approximate formula iron-aluminate as follows (Fe 0.77 0.23 ) 0.07 0.05 0.88 4 .
Chemical resistance of commercial refractory raw materials against Cu slag is critical to consider them as candidates for the production refractories used in metallurgy. In this study, we show comparative results corrosion four materials-magnesia chromite co-clinkers FMC 45 and 57, PAK, fused spinel SP AM 70-against aggressive, low-melting PbO-rich (Z1) determined by hot-stage microscopy (up 1450 °C) pellet test (1100 1400 °C). Samples were characterized after XRD, SEM/EDS, examination their...
Abstract Magnesium oxide (MgO) is one of the most important raw materials in many branches industry. a popular refractory material because its high refractoriness and resistance to basic slags environment. In cases, use MgO limited by properties, especially presence secondary phases like iron oxides. The amount distribution oxides can strongly influence technological properties depend on manufacturing method, particularly heat-treatment process. aim study was evaluate process ions magnesium...
Abstract The aim of the study was to characterize 0.8CaZrO 3 -0.2CaFe 2 O 4 composite structure with particular emphasis on role and position iron in function sintering temperature. paper presents results 57 Fe Mössbauer effect at room It found that increase temperature causes an amount incorporated ions CaZrO -crystal structure. Based spectroscopy analysis, it three different environments 3+ were observed obtained materials. Two them corresponded CaFe phase one associated substitution Zr 4+ by
The present study was devoted to an investigation of the synthesis conditions and influence Sn ions on production a CaZrO3 porous structure.Porous ceramics based with SnO addition were prepared by means pressureless sintering.The presents type starting materials firing procedures microstructures materials.Two different applied.The samples obtained from pure chemical reagents CaCO3 or CaO ZrO2.SnO added in mass fraction 2 %.The investigated terms phase composition XRD.The microstructure...
The aim of this study was to evaluate the influence time ageing on phase evolution paste from MgO-SiO2-H2O system. composed fine grained sintered magnesia and microsilica in 1:2 molar ratio water, with water solid equal 0,5. After preparation during specified up 180 days temperature 20° C. Phase composition mixture MgO SiO2 studied by XRD, DTA-TGA. analysis revealed that product reaction MgO, a probably poorly crystalline magnesium silicate.
