Densification characteristics of chromia/alumina castables by particle size distribution
The quality of the refractories applied on integrated gasification combined cycle should be a key factor that affects both the reliability and the economics of gasifier operation. To enhance the workability of chromia/alumina castables, three types of ultrafine alumina powder were added to improve the workability. Densification behavior of such castables in the presence of ultrafine alumina was...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولEffects of Cr2O3 on physical and mechanical properties of in-situ spinel containing castable
Increasing demands for cement, iron and steel industries for refractories with suitable workability in severe conditions (without any environmental risks), make the refractories’ researches to be an active area. Refractories containing Spinel has been developed with addition of chromia as a substitute in refractories using Magnesite - chromite. In this research, different amounts of Cr2O3 were ...
متن کاملChromia (cr2o3) Nanoparticles Synthesized by Using Cro3 via the Facile Solvothermal Process and Their Optical Properties
Chromia (Cr2O3) nanoparticles have been successfully synthesized via the facile solvothermal process, by using CrO3 in butanol and propanol as solvents. The functional groups of the samples were tested by the Fourier Transform Infrared (FTIR) spectroscopy. The as-synthesized nanoparticle sizes are calculated and confirmed to be 34 and 40 nm, by using X-ray Diffraction (XRD) and Transmission Ele...
متن کاملEvaporation of Cr2O3 in Atmospheres Containing H2O
Stainless steels in atmospheres containing H2O form a Cr2O3 scale in the early stage of oxidation. However, the Cr2O3 scale gradually degrades with time. In order to determine the effect of H2O on the deterioration of a Cr2O3 scale, evaporation behavior of Cr2O3 in N2-O2-H2O atmospheres was investigated. The rate of mass loss in a N2-O2-H2O atmosphere was found to be one order of magnitude high...
