چکیده

SiC-based ceramics are of great interest for various advanced applications. However, its fabrication requires high-temperature treatment at ~2000 – 2100 °С. In this study, we developed an approach based on low-temperature reactive spark plasma sintering to produce dense with superior mechanical properties. It was found that SPS temperature 1600 °C and introduction 10 15 wt.% mechanically activated non-oxide Ti–Si–C additive is required manufacture a theoretical density higher than 90%. Nonetheless, employing 5 the mixture 1700 °C, maximum ~ 98% achieved. The controlled formation decomposition in-situ Ti 3 SiC 2 MAX phase enables engineering enhanced compressive strength (550 MPa), elastic modulus (485 GPa), microhardness (32 which comparable best-reported ceramics. study has significant potential practical application in production purposes could be used further understanding development methods. • Ball mill mixing activates raw addictive powder but doesn’t affect composition Increasing enhances content situ facilitates nanocomposite ceramic structure shows characteristics

Synthesis and Sintering of Ti3SiC2–SiC Composites through Reactive Hot-Pressing of TiC and Si Precursors

MAX phases are an attractive class of layered solids that have recently attracted a great deal of attention due to their unusual and unique composition. The ternary compound Ti3SiC2 is an example of a material that combines the properties of ceramics and metals. As a ceramic, they are high stiff. Some of them are resistant to oxidation, creep, fatigue, corrosion. They are extremely refractory a...

Effect of Sintering Temperature on Structural, Dielectric, and Magnetic Properties of Multiferroic YFeO3 Ceramics Fabricated by Spark Plasma Sintering

Based on precursor powders with a size of 200-300 nm prepared by the low-temperature solid reaction method, phase-pure YFeO₃ ceramics are fabricated using spark plasma sintering (SPS) at different temperatures. X-ray diffraction (XRD) and scanning electron microscopy (SEM) reveal that the high-purity YFeO₃ ceramics can be prepared using SPS, while the results from X-ray photoelectron spectrosco...

Solid state sintering of very low and negative thermal expansion ceramics by Spark Plasma

Lithium aluminosilicate powder precursors of compositions Li2O:Al2O3:SiO2 as 1:1:2; and 1:1:3.11 were synthesized and sintered by the Spark Plasma Sintering technique. The sintering conditions were adjusted to obtain dense ceramic materials in an attempt to avoid the presence of a glassy phase. XRD and SEM images were employed for composition and microstructure characterization. The coefficient...
