“…The chemical stability of SiC, particularly its corrosion resistance in acidic and basic environments, is a key factor in its widespread application in various industrial sectors. In industries such as chemical engineering, energy conversion, and environmental engineering, equipment and materials often face harsh chemical attacks, necessitating the use of materials with extremely high chemical stability. ,, SiC exhibits outstanding performance under these conditions, demonstrating high tolerance against hydrochloric acid, sulfuric acid, nitric acid, and basic substances like potassium hydroxide and sodium hydroxide. Despite its renowned chemical stability, the specific etching reaction mechanisms, surface interface modification engineering, and the relationship between microstructure and performance of different crystal types of silicon carbide, in acidic and alkaline environments, remain topics worthy of in-depth study.…”

Silicon carbide, as a third-generation semiconductor material, plays a pivotal role in various advanced technological applications. Its exceptional stability under extreme conditions has garnered a significant amount of attention. These superior characteristics make silicon carbide an ideal candidate material for high-frequency, high-power electronic devices and applications in harsh environments. In particular, corrosion resistance in natural or artificially acidic and alkaline environments limits the practical application of many other materials. In fields such as chemical engineering, energy conversion, and environmental engineering, materials often face severe chemical erosion, necessitating materials with excellent chemical stability as foundational materials, carriers, or reaction media. Silicon carbide exhibits outstanding performance under these conditions, demonstrating significant resistance to corrosive substances such as hydrochloric acid, sulfuric acid, nitric acid, and alkaline substances such as potassium hydroxide and sodium hydroxide. Despite the well-known chemical stability of silicon carbide, the stability conditions of its different types (such as 3C-, 4H-, and 6H-SiC polycrystals) in acidic and alkaline environments, as well as the specific corrosion mechanisms and differences, warrant further investigation. This Review not only delves deeply into the detailed studies related to this topic but also highlights the current applications of different silicon carbide polycrystals in chemical reaction systems, energy conversion equipment, and recycling processes. Through a comprehensive analysis, this Review aims to bridge research gaps, offering a comparative analysis of the advantages and disadvantages between different polymorphs. It provides material scientists, engineers, and developers with a thorough understanding of silicon carbide's behavior in various chemical environments. This work will propel the research and development of silicon carbide materials under extreme conditions, especially in areas where chemical stability is crucial for device performance and durability. It lays a solid foundation for ultra-high-power, high-integration, high-reliability module architectures, supercomputing chips, and highly safe long-life batteries.

“…The amount of silicon waste slurry is expected to be increasing worldwide, as silicon wafer production increases. For instance, the fast-growing photovoltaic solar cells market achieved a cumulative growth rate of 35% between 2010 and 2019 [11]. As a consequence of this dynamic growth, the amount of the silicon slicing slurry wastes from the production of photovoltaic solar cells was nearly 160 000 Mg in 2017 [11].…”

“…Silicon slurry waste can be separated using physical and chemical methods or flotation. In particular, several methods have been developed to recover SiC particles from the silicon slurry waste such as sedimentation, centrifugation, magnetization, filtration, directional solidification, alloying process, phase-transfer separation, electrokinetic separation, froth flotation technologies and carbothermic reduction [5][6][7][8][9][10][11][12][13][14]. However, these methods require high-cost apparatus, complex processes and consume substantial amounts of chemicals generating additional wastes.…”

The paper presents an investigation on the feasibility of recovery of the highly valuable silicon carbide (SiC) from the slurry waste generated from silicon wafer production in the photovoltaic and semiconductor industry. Compared to the other techniques of recycling, a facile and low-cost method of waste treatment via heat drying followed by low-energy mixing in a shaker mixer was proposed. As the result of the treatment, the slurry waste was converted into a powdered form with dominant content of SiC. Separated SiC material was characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray powder diffraction, and sieve analysis. In addition, analyses of the bulk density, moisture content and melting test were carried out. As was confirmed by the physicochemical analyses, the dominant sieve fraction was in the range of 0.1-0.06 mm, the purity level was a minimum 99% mass of SiC, the moisture content -0.3%, the bulk density -1.3 g/cm 3 . The physicochemical characteristics of the material were crucial for understanding the material performance, assessment of the material quality and determining the perspective directions of the industrial application. The studies revealed that the material exhibited a high application potential as abrasive, especially in abrasive grinding and waterjet cutting.
