“…MgO has little effect on the porosity of the agglomerated by pure substances [50]. In the range of 0–2 mass% MgO addition, the reduction swelling index first increased and then decreased with the increasing MgO, and reached a peak value of 16.85% when MgO is 0.5 mass%.…”

It is imperative to reduce the pollution and energy consumption in the blast furnace ironmaking process. High pellets operation is a developing direction in the future. The function of blast furnace slag system cannot be ignored. In order to balance the MgO content in blast furnace slag and improve the metallurgical properties of pellets in the high pellets ratio operation, the research on MgO-bearing pellets is necessary. In this paper, the metallurgical properties of MgO-bearing pellets and the properties of blast furnace slag effect by MgO in different raw material conditions, especially for Vanadium Titanomagnetite, were analysed and summarized. This review provided a reference for the development of MgO-bearing pellets and the performance of blast furnace slag effect by MgO. It is hoped to reduce pollution and promote the technical progress of blast furnace ironmaking.

“…Firstly, ZrO 2 present in the purchased raw materials and the oxide layer on the starting material appeared harmful to the sintering performance [45]. In addition, complex chemical reactions took place in the matrix during sintering, and gas was produced during the reaction, which might be intercepted in the matrix at high temperature [46]. These were the reasons for the reduction of the sintering density (Figure 7a shows the residual porosity).…”

TiC ceramics have the characteristics of high melting point and density, and titanium reserves on earth are extremely large; therefore, TiC ceramics are considered ultra-high temperature materials with great research value. However, the development of TiC-based ultra-high temperature composites has been seriously hindered by their poor mechanical properties. At present, improvement of the mechanical properties of TiC is mainly accomplished by adding a second phase. In this paper, the research status of modified elements-, nitrides-, and metal-reinforced TiC matrix composites is presented. The microstructure, phase composition, and toughening mechanism of TiC matrix composites reinforced by a second phase are described. The influence of the reaction products on the matrix during the toughening process is also discussed.

Several studies have reported about different hydrogen production and storage materials. The use of metal oxides, particularly iron oxides, as hydrogen storage materials offers a promising solution to bridge hydrogen production and utilization. The iron‐steam process, dating back to the 18th century, leverages iron's ability to bind oxygen from steam, producing hydrogen and iron oxides. This study revisits the iron/iron oxide system for its dual application as a hydrogen storage medium and as an energy carrier in systems like fuel cells. When integrated with high‐temperature electrolysis and fuel cells, this system can efficiently operate between 600 and 1000 °C. The key to long‐term performance lies in understanding the formation and stability of oxygen‐binding structures. Stabilizing the iron oxides for cycling procedures with other metal oxides like Al2O3, SiO2, and CaO is inevitable. Ceramic‐stabilized iron oxide pellets offer advantages including high cycling capability, efficient charge/discharge operations, and potential syngas production. They are particularly suitable for heavy goods vehicles, short‐term storage, and large‐scale industrial applications. Critical process parameters for the iron oxide material and process design must be investigated if an accurate assessment of the performance of this hydrogen storage concept is to be transferred into efficient practice.
