steel research international, EarlyView.Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Effect of Fluxing Agent B2O3 on Melting Temperature of CaO-Based Refining Slag
Teshugang, 2009 Effects of B2O3 on melting temperature of two CaO-based refining slag series with low basicity [ ( CaO)/ (SiO2)=3 ~4] and high basicity [ (CaO)/(SiO2)= 5 〜7. 5 ] have been studied. Results indicate that B2O3is more available than Al2O3and CaF2to decrease

steel research international, EarlyView.The in situ agglomeration behavior of semisolid Al–silicate inclusions in Si‐killed steel is studied using high‐temperature confocal scanning laser microscopy. Particle motion and interparticle forces at the steel/argon interface are quantified and compared with a modified capillary interaction model.

A metallurgical route to solar-grade silicon [PDF]
The aim of the process is to produce silicon for crystallization into ingots that can be sliced to wafers for processing into photovoltaic cells. If the potential purity can be realized, the silicon will also be applicable for ribbon pulling techniques ...
