Engineering ceramics such as alumina, zirconia, silicon nitride and silicon carbide can now be manufactured reliably with reproducible properties. As such, they are of increasing interest to industry, particularly for use in demanding environments, where their thermomechanical performance is of critical importance, with applications ranging from fuel cells to cutting tools. One aspect common to virtually all applications of engineering ceramics is that eventually they must be joined with another material, most usually a metal. The joining of engineering ceramics to metals is not always easy. There are two main considerations. The first consideration is the basic difference in atomic bonding: the ionic or covalent bonding of the ceramic, compared to the metallic bond. The second consideration is the mismatch in the coefficient of thermal expansion. In general, ceramics have a lower coefficient of thermal expansion than metals and, if high tensile forces are produced in the ceramic, either as a consequence of operating conditions or from the joining procedure itself, failure can occur. The plethora of joining processes available will be reviewed in this article, placing them in context from both an academic and commercial perspective. Comment will be made on research reporting advances on known technology, as well as introducing 'newer' technologies developed over the last 10 years. Finally, reviews and commentary will be made on the potential applications of the various joining processes in the commercial environment.

“…However, it requires high nitrogen pressure and sintering temperature. On the other hand, alkaline earth oxides (i.e., SrO-MgO-CeO2) as new sintering additives were utilized to densify Si 3 N 4 at a lower sintering temperature and atmospheric nitrogen pressure [ 54 ]. Pressureless sintering of Si 3 N 4 doped with a combination of MgO and Y 2 O 3 has been successfully achieved by Ling et al [ 55 ].…”

“…However, it is still very challenging but rewarding to optimize the properties of Si 3 N 4 and to integrate scientific technologies to apply Si 3 N 4 materials to commercial products for clinical needs. Obviously, design methodology, near net shaping, machining, and quality control should also be carefully considered to produce highly reliable Si 3 N 4 implants with possible lower manufacturing costs [ 54 ].…”

Silicon nitride possesses a variety of excellent properties that can be specifically designed and manufactured for different medical applications. On the one hand, silicon nitride is known to have good mechanical properties, such as high strength and fracture toughness. On the other hand, the uniqueness of the osteogenic/antibacterial dualism of silicon nitride makes it a favorable bioceramic for implants. The surface of silicon nitride can simultaneously inhibit the proliferation of bacteria while supporting the physiological activities of eukaryotic cells and promoting the healing of bone tissue. There are hardly any biomaterials that possess all these properties concurrently. Although silicon nitride has been intensively studied as a biomedical material for years, there is a paucity of comprehensive data on its properties and medical applications. To provide a comprehensive understanding of this potential cornerstone material of the medical field, this review presents scientific and technical data on silicon nitride, including its mechanical properties, osteogenic behavior, and antibacterial capabilities. In addition, this paper highlights the current and potential medical use of silicon nitride and explains the bottlenecks that need to be addressed, as well as possible solutions.

“…9) Furthermore, vanadium boride, in analogy with TiB 2 , has a thermal expansion coefficient that differs most from that of boron carbide 5) and, consequently, an increase in the fracture toughness is anticipated if the proper composite design is developed. Mizutani et al 10) showed that, for case of particulate composites of SiC20 mol.% MeB 2 , ceramic composites with VB 2 exhibited the highest toughness. In addition, Tanaka et al 11) showed that the small addition of VB 2 (5 vol.%) to SiC also resulted a high fracture toughness of 4.6 MPa·m 1/2 .…”

The in situ synthesis and consolidation of B 4 CVB 2 eutectic composites by spark plasma sintering (SPS) is reported. The microstructure properties were determined for composites with the B 4 CVB 2 eutectic composition as functions of the VB 2 content and the VB 2 VB 2 interlamellar spacing. A change of VB 2 concentration from 45 to 48 mol.% resulted in the formation of the rodlike eutectic microstructure. Indentation fracture toughness values higher than 4 MPa·m 1/2 were identified for eutectic composites with interlamellar spacings between 0.9 and 1.2¯m. The composites obtained by SPS with a composition of 45 mol.% VB 2 exhibited a lower Vickers hardness (2324 GPa) and higher indentation fracture toughness (up to 4.5 MPa·m 1/2 ) than the eutectic composites with 48 mol.% of VB 2 .
