“…Silicon carbide ceramic was the earliest forms of artificial abrasives because of its high mechanical strength. Stable chemical properties, high thermal conductivity, thermal expansion coefficient, and other fine performance characteristics have allowed silicon carbide to become widely used in various fields such as coating materials, refractory, and metallurgy [1][2][3]. Solid state sintering is the key process of preparation of silicon carbide ceramics.…”

A real-time observation of the microstructure evolution of irregularly shaped silicon carbide powders during solid state sintering is realized by using synchrotron radiation computerized topography (SR-CT) technique. The process of sintering neck growth and material migration during sintering are clearly distinguished from 2D and 3D reconstructed images. The sintering neck size of the sample is presented for quantitative analysis of the sintering kinetics during solid state sintering. The neck size-time curve is obtained. Compared with traditional sintering theories, the neck growth exponent (7.87) obtained by SR-CT experiment is larger than that of the two-sphere model. Such condition is discussed and shown in terms of sintering neck growth, in which the sintering process slows down when the particle shape is irregular rather than spherical.

“…The use of monolithic ceramics for high pressure and high temperature applications is always limited by their lower toughness. Hence, particular attention is now being paid to investigations of the fibre-reinforced CMCs mainly for the automotive components and aerospace systems, such as windshields and gas turbine blades (Yilmaz, 2007;Boccaccini et al, 2003). However, many works have been devoted to glass and glass-ceramic matrix composites reinforced with commercially available * Corresponding author.…”

Glass and glass–ceramic matrix composites represent a very particular type of composite materials. As in most ceramic matrix composites, the reinforcements are mainly intended to increase the resistance to crack propagation, that is, the most significant weakness of the matrices, due to several toughening mechanisms. Unlike polycrystalline ceramic matrices, however, glasses offer the distinctive feature of viscous flow, being readily deformed and flowed in their low viscosity state, with the possibility of incorporating secondary phases at moderately high temperatures. Fibrous reinforcements (mainly C and SiC fibers) are at the basis of materials with impressive properties, for example, strength above 1 GPa, fracture toughness up to 35 MPa m 0.5 , almost zero thermal expansion, and service temperature up to 1500°C, but still facing high costs, although known for many years. Recent applications, such as that of “optomechanical materials,” that is, transparent materials with improved crack resistance, may stimulate research investments and production. As an alternative, dispersion‐reinforced composites, first seen as lower value category, owing to the limited improvements in fracture toughness, are currently the candidates for extensive industrial production, since the low cost treatments applied may be combined with complex combinations of different functionalities.
