Enhanced Mechanical and Thermal Properties of Waste Electric Porcelain-Based Solar Energy-Absorbing Thermal Storage Ceramics with Interwoven Mullite Structure

Crystals, Год журнала: 2025, Номер 15(1), С. 90 - 90

Опубликована: Янв. 18, 2025

This study addresses the environmental and resource challenges posed by growing volume of waste electric porcelain in power industry developing solar absorption thermal storage integrated ceramics (SATS ceramics) from porcelain. These SATS ceramics, which feature an exceptional mullite structure, were crafted through optimization sintering process. Notably, when sintered at 1400 °C with 11 wt.% magnetite content, resulting material boasts optimal short-clustered, ordered, interwoven columnar structure. structure endows a remarkable flexural strength 96.05 MPa specific heat capacity up to 0.6415 J/(g* °C) 300 °C, significantly enhancing its energy efficiency. research offers innovative insights into high-value utilization development materials, underscoring significant economic advantages.

Copper slag and red mud with high iron contents were discharged an annual global amount of 37.7 175 million tons but had low utilization rates due to wide reuse difficulties. Studies on their large-scale have become urgent. Thermal storage ceramic is a kind energy material high-added value potentially large market. In this study, method convert copper into thermal ceramics through fabrication process was proposed. Four samples prepared characterized by XRD SEM-EDS, as well physical property tests. The relationships among phase composition, microstructure, properties further discussed. results showed the from best flexural strength 68.02 MPa density 1238.25 J/g, both equal nearly twice those traditional heat materials like Magnesia Fire Bricks corundum. grain sizes mineral phases in significant impacts performance material. Increasing proportion could enhance performance. This study provides new perspective low-cost preparation iron-containing solid waste.

Stainable Utilization Strategies for Basic Oxygen Furnace Slag: Properties, Processing, and Future Directions

Metals, Год журнала: 2025, Номер 15(5), С. 537 - 537

Опубликована: Май 12, 2025

Steel slag, being the dominant solid byproduct in steelmaking, presents global challenges sustainable management, particularly regarding resource recovery of Basic Oxygen Furnace (BOF) which accounts for over 72% total slag generation. Through databases ScienceDirect, Web Science, and CNKI, using relevant key words, this review systematically investigates physicochemical properties mineralogical composition BOF elucidating intrinsic mechanisms underlying its low hydration reactivity volumetric instability. Pretreatment techniques have been demonstrated to effectively modulate these properties. Furthermore, valuable components can be efficiently recovered through methods including magnetic separation related technologies. elucidates existing across various utilization approaches steel while also identifying research priorities future development, thereby providing a systematic theoretical framework technical pathways advance slag.

Stabilization of thermal storage ceramics via the phase reconstruction of ferrotitanium slag and migration of Mg element

Journal of the American Ceramic Society, Год журнала: 2024, Номер unknown

Опубликована: Сен. 27, 2024

Abstract In this study, aluminum titanate/anorthite (Al 2 TiO 5 ‐CaAl Si O 8 ) ceramics were fabricated from ferrotitanium slag through phase reconstruction. Stabilization of the ceramic was achieved by migration Mg element into Al phase. The results indicated that optimal performance with addition 4 wt% MgO and 60 at 1370°C. exhibited bulk density 3.11 ± 0.01 g/cm 3 , thermal storage 1.51 kJ/cm expansion coefficient 3.40 × 10 −6 /°C (1000°C), respectively. Additionally, solid solution 2+ in lattice reduced formation microcracks enhanced mass transfer process. Consequently, sintering temperature decreased 1415°C to 1370°C while bending strength increased 61.25 1.05 MPa 75.92 7.72 MPa. Furthermore, finite simulation demonstrated higher led concentrated stress, potentially increasing possibility cracking. This research provides a new strategy for preparing low titanium‐containing waste.
