Abstract An integrated experimental and thermodynamic modeling study has been used to characterize phase equilibria in the Pb-Fe-O-S-Si system. The approach developed for investigation of this system, which involves use high-temperature equilibration, quenching, electron probe X-ray microanalysis, enabled overcome difficulties associated with high corrosive tendency condensed phases vaporizatio...

Hydroxyapatite (HA), chemical formula Ca10(PO4)6(OH)2, is a very popular bioceramic for orthopedic and dental applications. Although HA has excellent biocompatibility, its inferior mechanical properties make it unsuitable for load-bearing implant applications. Therefore,HA should be strengthened by a secondary phase to produce a composite that possesses robust mechanical properties. The aim of ...

In this paper, the acceleration effect of nickel (Ni) on direct nitridation process diamond-wire saw powder (DWSP) was investigated. The DWSP doped with Ni additives were nitrided at different temperatures. To study mechanism accelerated nitridation, thermodynamics Si-O-N-Ni and processes analyzed by FactSage 7.2 single-crystal silicon blocks also instead DWSP. results revealed that decreased t...

The steel production enhancement in recent decades has increased the solid waste generation plants. Due to increase environmental policies stringency, efforts have been made give them a more appropriate destination. In this context, internal reuse of these materials is solution often applied by industry reduce costs and decrease slag generation. Therefore, aim research replace calcitic lime lim...

This study uses a magnesiothermic reduction method to investigate the co-synthesis of zirconium boride, silicides, and oxide powder composites using ZrO2, B2O3, Si, Mg initial powders. The synthesis high-temperature ceramic powders is examined through milling durations, temperatures, excess magnesium addition. Thermochemical analysis probable reaction products was conducted by Factsage software...

To investigate the modification of type B inclusions in high-carbon hard-wire steel with Ca treatment, Si-Ca alloy was added to hard-steel, and composition, morphology, size, quantity, distribution were observed. The samples investigated by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS). experimental thermal results showed that effect inclusion better Al 0.0053% 0.0029% t...

Ash deposition-related issues adversely affect the thermal transfer and cause corrosion to biomass fired utility boilers. Various models have been proposed estimate slagging propensities for firing fuels of different origins. However, there is no reliable general applicable method that available assessing fuel without carrying out extensive experimental testing. In addition, empirical correlati...

This work investigates the transformation, release and fate of inorganic matter during fluidised bed gasification poultry litter also mixed with limestone as an additive. The litter, cyclone ash were characterised by means chemical fractionation analysis, well X-ray diffraction. Concurrently, species feedstock was measured in separate laboratory experiments using molecular beam mass spectrometr...

Abstract The goal of the current work is to develop a methodology study wetting behaviour two immiscible liquids at high temperatures, and investigate parameters which influence properties. between synthetic FeMn alloy slag has been investigated using sessile drop technique. Two experimental procedures were implemented under both Ar CO atmospheres: (a) placed next each other on graphite substra...

The CaCl2-CaF2-CaO phase diagram was investigated in the CaO low region (2-CaF2 and CaCl2-CaO binary diagrams, constituting ternary system, were first studied by Differential Scanning Calorimetry (DSC) measurements X-Ray Diffraction (XRD) characterization; a good agreement obtained between models calculated with FactSage® software (FTsalt database) present experimental data. As CaF2-CaO liquidu...
