Summary: The influence of BaO content on the network structure evolution and properties of glass-ceramics prepared from blast furnace (BF) slag was investigated. The results showed that a moderate addition of BaO enhanced the Si-based structure, decreased the Al-based structure, and improved the migration resistance of ions. The addition of BaO also resulted in the generation of diopside and augite, as well as densified structure with uniform distribution of crystals at 3 wt % BaO content.

Summary: This study investigated the effects of acidity coefficient on the properties of molten modified blast furnace slag and modified blast furnace slag fiber. The results showed that the acidity coefficient had an impact on the temperature range, melting temperature, and fiber-forming temperature of the slag. The acidity coefficient also influenced the crystallization temperature and fiber formability of the modified slag. The fibers prepared from the modified slag had smooth surfaces and were arranged in a crossed manner at the macroscopic level. The acidity coefficient affected the average fiber diameter and slag ball content of the fibers.

Summary: The crystallization and viscosity of modified blast furnace slag are important factors for fiber formation. This study investigated the crystallization behavior of modified blast furnace slag under continuous cooling conditions using differential scanning calorimetry, and established the crystallization kinetics with different acidity coefficients. The results demonstrated that the crystallization phases of slag with acidity coefficients of 1.05 and 1.20 were Melilite and Anorthite, respectively. The crystal growth mode of slag changed with acidity coefficient, and the crystallization activation energy also varied. The change in viscosity was influenced by crystal size and content.

Summary: This study investigated the effect of Al2O3/SiO2 mass ratios on the viscosity and structure of a CaO-SiO2-MgO-Al2O3-BaO slag system. The results showed that increasing the Al2O3/SiO2 ratio decreased viscosity and weakened the Si-based and Al-based structures. The study also found that increasing the Al2O3/SiO2 ratio led to depolymerization of the network structure.

Summary: The viscosity of high-titanium blast furnace slag with varying levels of TiO2 content, Al2O3 content, and basicity was measured using the rotational cylinder method at temperatures between 1653-1773 K. XRD was used to analyze the phase composition of the slag, while FactSage software was used to calculate the phase diagram. FT-IR was employed to analyze the ionic network structure of the slags. The results indicate that TiO2 depolymerizes the silicate network structure, reducing viscosity at high temperatures, while increasing Al2O3 content generates a more complex silicate, increasing viscosity. The basicity of the slag also plays a role in viscosity, with higher basicity leading to lower viscosity above 1733 K. The presence of perovskite significantly affects the viscosity of the slag. This study provides a comprehensive understanding of the relationship between composition and viscosity of high-titanium blast furnace slag, which is crucial for enhancing production efficiency.

Summary: The isothermal and non-isothermal crystallization behavior of blast furnace slag with different CaO/SiO2 ratios was observed using confocal scanning laser microscopy (CLSM). The kinetics of crystallization and precipitation of crystalline phases were analyzed using FactSage 8.0 and X-ray Diffraction (XRD). The results showed that the crystals morphology changed with increasing CaO/SiO2 ratio, and the onset crystallization temperature was higher at larger CaO/SiO2 ratios. The crystals morphology changed gradually with the increase of CaO/SiO2 ratio in the isothermal crystallization process, and the incubation period became shorter. XRD analysis revealed the presence of different crystalline phases at different temperatures and CaO/SiO2 ratios.

Summary: The effect of CaO/SiO2 ratio on the crystallization behaviors, mechanical properties, and acid and alkali resistance properties of Ti-bearing blast furnace slag-based glass ceramics was investigated. The results showed that the crystallization temperature decreased and crystallization ability increased with higher CaO/SiO2 ratios. The vickers hardness gradually decreased, while the flexural strength first increased and then decreased with an increased CaO/SiO2 ratio. The glass ceramics with CaO/SiO2 = 0.5 exhibited the highest flexural strength and good acid and alkali resistance.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
