Synthetic fluorspar can be produced from waste calcium fluoride slurry settled on dumpsites located near Cracow centre. Synthetic fluorspar exchanges natural raw material used in the metallurgical industry. To obtain grained synthetic fluorspar, calcium fluoride slurry should be calcinated in rotary kilns at temperatures of 900-1100K. Grain size and compression strength strongly depends on calc...

A method of joining metals with semi-solid slurries is presented. Experiments have been carried out using a model alloy of Sn-Pb to demonstrate the concept. The advantages of this process are a controlled microstructure of the weld, lower post-welding stresses and a small heat affected zone. Tensile tests have been performed, showing a weld strength comparable to bulk material strength. Key fac...

Insufflated talc is probably the most effective agent for creating a pleurodesis both in the clinical situation and in animals. However, the insufflation of talc requires an invasive procedure such as thoracoscopy or thoracotomy. Recently, there have been reports that talc in a slurry was effective in the clinical situation. The objective of this project was to determine whether talc in a slurr...

The use of elastomer additives to solve the problems in oil well cementing has been investigated in recent years by several research groups in the petroleum industry. This study includes the laboratory examination of the effect of elastomer additives on the physical properties of heavy-weight oil well cement. In the research process, a candidate well is selected and the properties of the cement...

atom transfer radical polymerization (atrp) of styrene was carried out at 105°c and a monte carlo simulation was employed to model the system. the variations of monomer conversion, the initiator concentration, average molecular weight, and molecular weight distribution were evaluated as the reaction proceeded. according to the results obtained, for similar reaction time, monomer conversion is h...

This review summarizes and discusses the analytical methods and techniques described in the literature for hydride generation as a mode of slurry sample introduction into atomization cells. A brief comparison of detection limits for analytical atomic absorption methods and practical applications to analytical samples that utilize slurry hydride generation is discussed. The current state-of-the-...
