The Effect of Carbon Nanoparticles and Calcined Alumina on Mechanical Properties and Corrosion Resistance Behavior of the Magnesia Carbon Refractories
Nowadays, magnesia carbon refractories are very important for the iron and steel industries. It is due to their unique properties, such as low wet ability with melt iron and steel. Therefore, it is important to extend the life of the refractory. In this research, the effect of calcined alumina and nano carbon on mechanical strength and corrosion resistance against slag in magnesia carbon refrac...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولLow-Temperature Sintering of Alumina with Liquid-Forming Additives
Simultaneous application of colloidal processing and liquidforming additives to alumina resulted in a sintered density of >99% in 1 h at a temperature as low as 1070°C for a commercial high-purity alumina powder at a total dopant level of 2 mol%. The additives were 0.9% CuO + 0.9% TiOz + 0.1% B 2 0 3 + 0.1% MgO. At higher temperatures or after prolonged sintering, the doped alumina ceramic deve...
متن کاملEffect of Alumina Addition to Zirconia Nano-composite on Low Temperature Degradation Process and Biaxial Strength
Ceramic dental materials have been considered as alternatives to metals for dental implants application. In this respect, zirconia tetragonal stabilized with %3 yttrium, is of great importance among the ceramic materials for endosseous dental implant application. Because of its good mechanical properties and color similar to tooth. The aim and novelty of this study was to design and prepare Y-T...
