[Physical properties and metal elutions of the thirteen molten slags produced from incinerated ash].
In recent years, there have been many attempts to reuse molten slag. Molten slag is obtained through further treatment of incinerated ash produced in the disposal process of garbage or sewage sludge and is used in building materials, such as brick. To establish the safety of such slag, its physical properties and metal contents were investigated in this study. After examining the physical and c...
متن کاملInfluence of Wettability and Reactivity on Refractory Degradation – Interactions of Molten Iron and Slags with Steelmaking Refractories at 1550°C
Refractories, materials that can withstand high temperatures, play an important role in the iron and steel sector which alone accounts for ~70% of total refractories pro‐ duced. In this chapter, detailed wettability and interfacial phenomena investiga‐ tions on alumina-carbon and zirconia-carbon refractories at steelmaking temperatures. The wettability between refractory substrates and molten i...
متن کاملWall slip of molten high density polyethylene. I. Sliding plate rheometer studies
Experiments were performed in a sliding plate rheometer with a high density polyethylene to determine the conditions for the onset of slip and the relationship between slip velocity and shear stress. It was found that melt slip occurs at a critical shear stress of approximately 0.09 MPa in both steady and transient shear tests. The effect of the presence of a layer of fluorocarbon at the interf...
متن کاملSynthetic studies on leupeptins and their analogs.
Leupeptins, fermentation products of various strains of Actinomycetes^ showed strong antiplasmin activity2) and were identified as being a mixture of two major components, leupeptin Ac-LL (acetyl-L-leucyl-L-leucyl-DL-argininal, 1) and leupeptin Pr-LL (propionyl-L-leucyl-L-leucyl-DL-argininal, 2), and their analogs containing isoleucine or valine in place of one or two leucine residues of 1 or 2...
متن کاملStudies on sintering process of synthetic hydroxyapatite.
In this study the effect of sintering process in different temperatures on microstructure and morphological properties of sintered hydroxyapatite (HAp) was investigated. HAp powder was prepared by wet precipitation method from following reagents: Ca(OH)2 + H3PO4 in an alkaline conditions. Thermal analysis (TA), X-Ray diffraction method (XRD), FT-IR spectrometry (FT-IR) and scanning electron mic...
