“…In the chemical industry, many reaction processes are required to be conducted under high-temperature, high-pressure, or strongly corrosive conditions. Silicon carbide, because of its exceptional chemical stability, high-temperature resilience, and excellent thermal conductivity, emerges as an ideal material for manufacturing chemical reactors. − SiC reactors are capable of handling highly corrosive chemicals such as strong acids and bases, as widely applied in the production of silicates, fertilizers, and dyes and in the refining and petrochemical industries. Compared to traditional materials, SiC reactors provide higher thermal efficiency, reduce energy consumption, and, due to their outstanding corrosion resistance, significantly lower maintenance costs and downtime.…”

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.

“…11 The former method introduces sintering aids to form liquid phase to promote sintering, but sintering aids will cause segregation of the second phase at the grain boundary, which is unfavorable to high temperature performance of porous SiC ceramics, and the sintering temperature is still higher than 1400 • C. 12,13 The latter method utilizes the second phase (added or in-situ reaction formed) to combine SiC particles, which can reduce sintering temperature remarkably. 14 The bonding phases used for porous SiC ceramics commonly include silica (SiO 2 ), 15 silicon nitride (Si 3 N 4 ), 16 mullite (3Al 2 O 3 ⋅2SiO 2 ), 17 cordierite (2MgO⋅2Al 2 O 3 ⋅5SiO 2 ), 18 silicon oxycarbide (SiOC), 19 and sodium borate (Na 2 B 4 O 7 ⋅10H 2 O). 20 Among these bonding phases, SiOC is the most attractive because the performance of which is similar to that of SiO 2 , the initial oxide of SiC powders, and has a significant binding effect on SiC particles.…”

Porous SiC ceramics have been used in high temperature flue gas filtration fields because of their excellent properties such as high strength, high temperature resistance, corrosion resistance, and long service time. This work reports the porous SiOC-bonded SiC ceramics prepared at low temperature. The properties of porous SiC ceramics were first investigated with silicone resin content from 10 to 25 wt%, and then the effects of different pore-forming agent contents on the behaviors of porous SiC ceramics were discussed by adjusting poly (methyl methacrylate) PMMA microbeads from 5 to 20 wt%. The prepared porous SiC ceramics showed apparent porosity from 17.3% to 57.7%, compressive strength from 6 to 216 MPa, and Darcy permeability k 1 ranging from 7.02 × 10 −14 to 1.45 × 10 −12 m 2 . The corrosion behavior of porous SiC ceramics was investigated in acidic and alkaline media. The porous SiC ceramics showed better corrosion resistance in acidic solutions.

A simple and high‐efficiency method is proposed to synthesize hierarchical ZSM‐5 zeolites with micropore and multistage mesopores by adopting water‐soluble carbon dots (CDots) with various size distributions, such as 1‐stage size distribution of CDots‐1 of around 23 nm, 2‐stage size distribution of CDots‐2 of 6 and 9 nm, 3‐stage size distribution of CDots‐3 of 5, 8, and 18 nm. The abundant OH and COOH groups on the surface of CDots provide high solubility in water. The characterization techniques confirmed that the dual‐porous h‐ZSM‐5 (MIcro–mEsopores) and multi‐porous h‐ZSM‐5 (MIcro–mEso–mEsopores), h‐ZSM‐5 (MIcro–mEso–mEso–mEsopores, M‐IEEE) catalysts are obtained. Notably, the hierarchical ZSM‐5(M‐IEEE) catalyst with micropore of 0.55 nm, two small mesopores of 4.8 and 7.4 nm, and one large mesopore of 17.5 nm show excellent catalytic performance with the highest 1,3,5‐triisopropylbenzene (TIPB) cracking conversion (97.3%) and high stability. Similarly, the h‐ZSM‐5(M‐IEEE) shows the high ethanol to olefins conversion (100%). The improved catalytic activity can be attributed to the more efficient diffusion of reactants and products in the crystals with the help of multistage mesopores, improved anti‐coking stability, combined with the effect of suitable acidity, and the increased accessibility of the acid sites.
