A systematic approach has been followed in the production and characterization of Pd foils to be used in excess heat production experiments [1][ 2] . Starting with a metal foil as supplied, palladium samples have been fabricated and characterized in a step by step process, and then subjected to electrolysis deuterium loading. The characterized metallurgical properties include the main grain siz...

Present society challenges, including metal scarcity, recycling, and environmental restrictions, resulted in the increased complexity variability of metallurgical feed streams. Metallurgical processes involving complex lead copper-containing slag matte phases are now commonly used response. Optimization existing development new require fundamental information on slag–matte phase equilibrium. De...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The publication presents the most recent results of research conducted in metallurgical enterprises which build Polish metallurgical sector. Three main areas of restructuring were tested, that is repair restructuring, development restructuring and adaptation restructuring. For each t...

Recent excavations made by University of Lecce in Piazzetta Epulione and Piazza Castromediano (Lecce) have produced structures and artifacts related to metal-working. Most of the evidence dates back to the Roman period; traces of metallurgical activity can also be traced to the periods preceding and following the Roman period. Iron slags and semi-finished objects have been found in Piazzetta Ep...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...

Dobrotă, Faculty of Economic Sciences and Business Administration, “Constantin Brâncuşi” University of Târgu-Jiu, Romania. The purpose of this paper is to identify the influence of degree of indebtedness, the level of equity capital and the net result on the value of metallurgical companies, represented by their marke...

The photovoltaic and the semiconductor industries are in growth and it is necessary to supply a large amount of silicon to maintain this growth. Since silicon is still the best material for the manufacturing of solar cells and semiconductor components so the pure silicon like solar grade and semiconductor grade materials are demanded. There are two main routes for silicon production: metallurgi...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland Before metallurgical enterprises started implementation of marketing activities they had to go through restructuring processes which included all areas of their market activities. Privatised metallurgical enterprises after economic transformation gradually implemented marketing to th...
