There are metabasite exposures inside ophiolitic belt of northwest Sabzevar that metamorphosed under high pressure granulite facies. On the basis of mineralogical paragenesis, reactional textures between different mineralogical assemblages, textural and mineralogical relations between inclusion and porphyroblast and stability fields of different mineralogical assemblages, five stages of evoluti...
In this study, a composite of bioactive glass (BG) and cordierite (BG-cord) was proposed to increase the strength bioactivity BG. Both BG were separately synthesized with method melting, then, they used fabricate BG-cord variation sintering temperature (600 1000 °C). The highest diametral tensile (DTS=30.54 MPa) shown by at 925 ºC. Bioactivity tests conducted soaking in Hank’s balanced salt sol...
In this experimental study, effects of H2O on the use ethanol as reducing agents were investigated Ag-Pt-W-Ti/Cordierite catalyst. catalyst was synthesized using impregnation method for selective catalytic reduction (SCR) NOx. To investigate addition NOx conversion ratios, tests carried out at 200-270 ° C under 30000 h-1 GHSV three different reductants (ethanol, 5 %H2O - 95 %ethanol, 10 90 %eth...
This article explores the factors that influence color of blue iolite, which is gem-quality variety cordierite mineral. The X-Rite SP62 portable spectrophotometer was used to measure in CIELAB space. ED-XRF and UV–vis were for analysis. results show iolite contains chromophore elements Fe Mn, but effect on not significant due low Mn content. lightness L* hue angle h° are mostly determined by it...
