چکیده
Abstract Direct emissions due to the use of carbon-based fossil-reducing agents contribute overall CO 2 pyrometallurgical production processes. This study investigated replacement fossil coke by silicon-rich cutting waste from solar wafer process produce ferrochrome in an electric arc furnace. Laboratory test work and thermochemical simulation were carried out examine product quality at various additions lime. The experimental trials resulted products accord with international standards, however, adjusting slag composition addition lime was necessary, otherwise high silicon contents alloys obtained. Due highly exothermic reaction iron- chromium oxides, silicothermic reduction results a decreased specific energy consumption compared carbothermic according simulation. Low phosphorus sulfur alloy might result premium prices, aiding economic viability process. Graphical

Towards ultra-thin plasmonic silicon wafer solar cells with minimized efficiency loss
The cost-effectiveness of market-dominating silicon wafer solar cells plays a key role in determining the competiveness of solar energy with other exhaustible energy sources. Reducing the silicon wafer thickness at a minimized efficiency loss represents a mainstream trend in increasing the cost-effectiveness of wafer-based solar cells. In this paper we demonstrate that, using the advanced light...
متن کاملHydrophobic silicon wafer bonding
Wafers prepared by an HF dip without a subsequent water rinse were bonded at room temperature and annealed at temperatures up to 1100 “C. Based on substantial differences between bonded hydrophilic and hydrophobic Si wafer pairs in the changes of the interface energy with respect to temperature, secondary ion mass spectrometry (SIMS) and transmission electron microscopy (TEM), we suggest that h...
متن کاملLecture 21: Silicon wafer manufacturing
The first step in integrated circuit (IC) fabrication is preparing the high purity single crystal Si wafer. This is the starting input to the fab. Typically, Si wafer refers to a single crystal of Si with a specific orientation, dopant type, and resistivity (determined by dopant concentration). Typically, Si (100) or Si (111) wafers are used. The numbers (100) and (111) refers to the orientatio...
متن کاملIn-Situ Investigation of Wafer-Slurry-Pad Interactions during CMP
The objective of this project is to acquire in-situ data during chemical mechanical planarization (CMP) including slurry film thickness and flow, wafer-pad contact, waferscale friction, and small-scale shear force measurements. The unifying project goal is to utilize a consistent set of experimental data to develop better physical understanding of material removal rate (MRR) and polish quality ...
متن کاملGarlic: An Alternative to Antibiotics in Poultry Production, A Review
In last decade, the uncontrolled use of antibiotics as growth promoter for livestock has led to the appearance of antibiotic-resistant pathogens and increased risk of infectious diseases. This situation has triggered intensive research efforts to find safe alternative strategies. Certainly, the plants and vegetables and their derivatives as natural safe substances could be good candidates in th...
