[ 1 ] - بررسی اثر استفاده مجزا و همزمان از پیونددهنده‌های فسفاتی، سیلیکاتی و بوراتی بر خواص فیزیکی و مکانیکی دیرگدازهای یکپارچه منیزیا-کربن
دیرگدازهای منیزیا- کربن کاربردهای گسترده‌ای در قسمت‌های مختلف صنعت فولادسازی از جمله کنورتورها، کوره‌های قوس الکتریکی و پاتیل‌های فولادسازی دارند که به خاطر خواص دیرگدازی عالی آن‌ها می‌باشد. با توجه به اینکه در حوزه مواد دیرگداز کربنی بی‌شکل به خصوص مواد قلیایی در حال حاضر کاربردهای وسیع صنعتی وجود دارد، در پژوهش حاضر استفاده مجزا و همزمان از پیونددهنده‌های فسفاتی، سیلیکاتی و بوراتی در حضور آب ...
[ 2 ] - Ti-6Al-4V Synthesized by Mechanical Alloy Method and Mechanical and Bioactivity Properties of Ti-6Al-4V/HA-Clay Nano composite
Nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. Hydroxyapatite (Ca10 (PO4)6(OH)2, HA) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. Firs...
[ 3 ] - The Role of Nano Sic Whiskers on the Strength and Density of Aluminum Silicate-SiC-C Compounds as a Reinforced Steel Refractory
This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...
[ 4 ] - The Role of SiC and Different Binders on Mechanical Strength and Compaction of Silica Based Refractories Materials
Silica refractory bricks are used especially in the metallurgical industries, due to desirable properties such as high melting point, rigidity, and high temperatures strength. In this research, different amount of SiC were added to Silica refractory containing different binders such as Borax, Boric acid, Calcium nitride, Sodium tri poly phosphate, Sodium hexa meta phosphate (SHMP) and lime. Phy...
[ 5 ] - 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...
[ 6 ] - Photocatalytic Removal of NOx Gas from Air by TiO2/Polymer Composite Nanofibers
Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...
