“…SiC with porous structure is a type of tailored ceramic substance that has attracted to a wide range of high-temperature engineering application fields. Due to its minimal density, strong heat resistivity, reduced thermal conductivity, and excellent mechanical qualities at extreme temperatures this porous ceramic also preferred in metallurgical field and chemical industries [160][161][162][163][164]. Due to its considerable importance in high temperature applications, this siliconbased ceramics such as SiC and Si 3 N 4 are being explored significantly.…”

This review paper aims to look at silicon-based ceramic matrix composites and infiltration-based approaches for them. There are many different types of infiltration-based manufacturing processes, each with its own set of features. The best technique is chosen depending on the needs and desired attributes. With these considerations in mind, any type of infiltration might be selected to meet the requirements. Silicon-based ceramics has been highly used in the fields of aerospace, medical, automobile, electronics, and other various industries so it is important to study about their applications as well. This review outlines the evolution of composites from early 7000 BCE to composites today and discussed about various infiltration techniques for manufacturing silicon based ceramic matrix composites. This article also gives the comprehensive review of general characteristics and mechanical properties of silicon-based composites used in a variety of engineering sectors. The application section entails the wide range of engineering fields with consideration of infiltration techniques, which would be helpful for researchers to study and correlate the different infiltration techniques for end applications.

“…Silicon carbide (SiC) is an intriguing material owing to its remarkable properties and versatility, which make it suitable for numerous industrial applications. [1][2][3][4][5][6][7][8] Porous SiC ceramics with excellent mechanical properties, [9][10][11][12][13][14] high chemical stability, [15][16][17][18][19] good permeability, [20][21][22][23][24] and controllable thermal [25][26][27] and electrical properties [28][29][30] have gained immense attention for both structural and functional applications. Although the practical use of SiC has mostly been limited to structural applications, it has been extensively investigated recently [25][26][27][28][29][30][31][32][33][34][35] for advanced functional applications owing to its semiconductivity.…”

Porous silicon carbide (SiC)‐based ceramics are widely used in numerous applications of technical importance owing to their exceptional structural (e.g., excellent chemical, mechanical, and thermal stability) and functional (e.g., controlled electrical resistivity) properties. Porous SiC with controlled electrical resistivity is required for various advanced applications, for example, power electronic devices, semiconductor processing parts, fusion reactors, thermoelectric energy conversion, electromagnetic shielding, and environmental applications such as heatable filters. The electrical properties of sintered porous SiC are significantly affected by its chemical composition, processing conditions, and microstructure. This article reviews the influence of certain critical factors, such as the polytype, doping conditions, porosity (%), additive composition (oxide additives, element additives, metal nitride/carbide additives, etc.), and processing conditions on the electrical resistivity of porous SiC. Novel applications of porous SiC with controlled electrical resistivity are also discussed in this review.

“…The most important factor to be addressed for a rapid high temperature change application is the ability of the glass ceramics to resist thermal shock. The thermal shock resistance properties of LAS glass-ceramics depend not only on the anisotropy CTE but also on the flexural strength [11]. In order to avoid possible cracks and fractures due to thermal stress, higher flexural strength is vital for better thermal shock resistance properties.…”

In order to determine the correlation of flexural strength and thermal shock resistance properties, the sintering behavior of Li 2 O-Al 2 O 3 -SiO 2 (LAS) glass-ceramics at different sintering treatment times and the effect of thermal shock cycles on LAS glass-ceramics were investigated. The LAS glass-ceramics were isothermally treated at 1100°C from 1.5 to 4.5 h. Phase transformation of major crystalline of β-spodumene and minor crystalline of ZrTiO 4 revealed unchanged as sintering treatment time increased. The physical properties of LAS glass-ceramics that were sintered for 3.5 h demonstrated an increased density (2.45 g/cm 3 ) and less porosity percentage (0.62%). The prolonged sintering treatment affected the microstructure whereby the mean grain size increased from 0.55 to 0.67 µm which also demonstrated the increase of microhardness in the range between 3.90 and 5.47 GPa. The flexural strength of LAS glass-ceramics revealed an enhancement of 158 MPa when sintered for 3.5 h. The thermal shock resistance properties were assessed at 500°C from one to seven cycles via thermal shock tests. After four thermal shock cycles, LAS glass-ceramics showed an improvement of 82% of residual strength from its original strength, due to a decrease in the formation of pores and an increase in the crystallinity and percentage of β-spodumene.
