Introduction Desulphurization of steel at ladle treatment of metal is one of the important technological operations. The successful course of the desulfurization process is provided by fire refining slag with specific chemical composition, usually based on calcium oxide. The duration of mixing of the metal with the slag in inert gas, the early formation of refining slag, then optimization of the metal oxidation providing the formation of iron oxide FeO in the slag to be less than 0.5 % able…

2.2. Instrumentation The residual concentration of metal ion in the filtrate were analyzed by GBC, Sensaa Series Atomic Absorption Spectrometry (computerized AAS) with air-acetylene flame under the optimum instrumental conditions as shown in (Table 1). The solution pH was measured using digital pH meter (Hanna instrument model HI 8519, Italy). Fourier transform infrared (FT-IR) spectra were measured on Nicolet is 10 FTIR spectrometer in the range of (4000 to 400 cm-1). Scanning electron…

Abstract The paper present the investigation on the effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be…

(1) Basic Substance. The basic substance used to make both steel and cast iron (gray and malleable) is the metal, iron in the form of pig iron. Pig iron is produced from iron ore, which occurs chiefly in nature as an oxide, the two most important oxides being hematite and magnetite. (2) Iron Ore. Iron ore is reduced to pig iron in a blast furnace, and the impurities are removed in the form of slag (figure 2 on the following page). Raw materials charged into the furnace include iron ore, coke,…

and compound of Minoxidil is C9H15N50, made entirely of nonmetals with the molecular weight being 209.2483 g/mol, the UIPAC name being 3 hydroxy, 2 imino, 6 piperidin, 1 ylpyrimidin, and 4 amine. The percentage composition of carbon being 51.65, hydrogen being 7.24, nitrogen being 33.47, and oxygen being 7.64. The definition of solubility is the quantity of any given substance that can be dissolved in the other, or the maximum amount of solute that can be dissolved in a solvent, which is why…

2.1 New semi empirical formula for of mass attenuation and energy absorption coefficients Most of the tissues of human organs consisting of elements such as H, C, N, O ,Ca ,P, Na, Mg, S, CI ,K ,Fe and I in their elemental composition. We have studied the variation of mass attenuation and energy absorption coefficients with atomic number at different energies for the elements which are constitutes of tissues of human organs. It has been proposed the empirical relations for mass attenuation and…

(Na2S) solution under constant stirring for another 1 hours. The prepared samples were yellow in color indicating the formation of CdS nanostructures. Cadmium acetate was dissociated into Cd+2 ions. After adding ammonia solution, it formed the cadmium complex. This complex solution was then reacted with the sulfur ion from Na2S and results…

TITLE: INTRODUCTION: Alka-Seltzer is used to reduce pain, inflammation, heartburn etc. It is an antacid. When it is dissolved in water, it produces carbon dioxide filled air bubbles. It is represented by CO2.(1) Alka-Seltzer consists of citric acid and aspirin. Bicarbonates are formed when the tablet is dissolved. When it is mixed with citric acid, then the acid reacts with bicarbonates and water, carbon dioxide are formed.(1) When Carbon and oxygen bonded, then carbon dioxide gas is…

Methane gas has numerous uses in its natural gaseous form. It is one of the best fuel sources and due to its abundance it has promising benefits as compared to the oil gases whose prevalence is limited making them more expensive. However, a major hiccup exists in its storage and transportation since the most conveniently used form is its liquefied form. This issue has for limited the volumes transported for the long time since the liquid occupies much more space as it could in a powder form. In…

Experiment Summary The purpose of this experiment was to determine the copper content of brass using iodometry. This was accomplished by creating a thiosulfate solution and standardizing it by titrating using a known amount of KIO3. The second part of the experiment involved preparing a brass sample and allowing copper to react with excess iodide to form I2. The resulting I2 was then titrated with the thiosulfate standard. Both the molar concentration of thiosulfate and the weight % copper…
