“…This may be due to formation of high atomic mass crystalline barium neodymium borate phase Ba 3 Nd(BO 3 ) 3 instead of relatively less dense BaB 2 O 4 phase. The density of controlled crystallized glasses is affected by a combination of factors, the most significant of which is the density of the crystalline phases formed 36 – 38 . Another factor may be affecting the density of the synthesized glass–ceramic is formation of fine microstructure with increasing the Nd 2 O 3 /B 2 O 3 replacement.…”

In the present study, a novel glass system containing Neodymium(III) oxide with BaO, Al2O3, and B2O3 were created via a popular melt-quenching technique. Nd2O3 were added, in different concentrations, instead of B2O3 to study its impact on the crystallization, and electro-magnetic behaviors of the prepared poly-crystalline materials. Thermal characteristics via DTA, XRD and SEM techniques were involved to explore the crystallization and structural properties. The magnetic parameters of the prepared glass–ceramics were studied by VSM measurements. As well the electric properties were also explored. BaB2O4 and Al(BO3) phases were firstly crystallized then Ba3Nd(BO3)3 phase was incompletely precipitated instead of BaB2O4 phase owing to Nd2O3 additions. As well, the internal structure was modified from coarse crystals to fine grain microstructure. The crystallization study proved that the addition of neodymium improved the crystallization process of the BaO–Al2O3–B2O3 glass system. The VSM and conductivity analysis for the crystalline materials proved that the Nd2O3/B2O3 substitutions led to an increase in the electrical and magnetic parameters of the investigated materials. The data obtained from the prepared crystalline specimen showed that these materials are with a distinct and promising ferro-electrical property for use in diverse modern applications.

“…For example, Khater used blast furnace slag and EAFS to prepare glass‐ceramics, as shown in Figure 2f–i, the main phase in the prepared glass‐ceramics was gehlenite when the temperature was low, and the main phase in the prepared glass‐ceramics was anorthite when the temperature was high. [ 22 ] In efforts to reduce costs and minimize the addition of nucleating agents, Huang et al [ 23 ] proposed the co‐preparation of pyroxene‐based microcrystalline glass using BFS containing less than 20% titanium and chromite slag. Figure 2j–o shows the main crystal phase in the glass‐ceramics.…”

The high‐value utilization of blast furnace slag (BFS) and steel slag (SS) as a valuable resource in the field of carbon reduction represents a green revolution, and also is an indispensable path toward breaking through resource and environmental constraints and achieving high‐quality, sustainable development through solid waste utilization in the steel industry. Achieving resource recycling while harnessing the untapped latent energy of resources and exploring their carbon sequestration capabilities has become a crucial avenue for further valorization through waste utilization. BFS and SS discharged from iron‐making or steel‐making furnaces carry a significant amount of latent heat, especially the calcium oxide component in SS, which gives it a unique advantage in the field of comprehensive BFS and SS utilization and carbonation‐based SS utilization. This article discusses the current research status of low‐carbon‐waste‐heat utilization in the production of microcrystalline glass, cementitious materials, functional adsorbents, and other products through front‐end modification of molten BFS and SS. This report also provides an overview of carbon capture by utilizing BFS and SS, offering insights into the research directions for subsequent heat recovery, online quality adjustment, high‐value utilization, and carbon sequestration using BFS and SS in the steel industry.
