“…The ion exchange was found not to cause significant structural changes but significantly improved the strength and toughness of the material (Figure 3C,D). Manufacture improvement: in the production of DGC, the proper control of grain size, 60 crystallinity, 61 and sintering density 49 optimizes the final properties of the material, and different manufacturing methods can produce different results, the choice of which also needs to be considered to the chemical composition. When the traditional manufacturing process is given digital processing techniques, researchers need to care about more factors, which will be discussed in detail in Chapter 3.…”

As a subserie of the dental ceramic material family, glass–ceramics are favored for their excellent aesthetic properties. The feasibility of current commercially available dental glass–ceramics applications has been proven, while the assurance and development of more functional properties for them are still being explored. Effective utilization of various modification mechanisms by adjusting the chemical composition and microstructure is essential to improve the mechanical properties, aesthetic properties, and other properties such as biocompatibility of dental restorative materials. Among them, the mechanical properties of restorations should take into account the mechanical properties of glass ceramics and the final restoration (restoration and tooth set) in the mechanical behavior. This paper provides an overview of the chemical composition design, classification of microstructure, property requirements, and strengthening methods applied to dental glass–ceramics, including ion exchange, chain effects, heat treatment modulation, and strengthening mechanisms. In addition, research on traditional hot pressing, subtractive manufacturing, and newly developed additive manufacturing in glass–ceramics are systematically presented. Finally, the tendency of dental glass–ceramics was forecasted by analyzing the relationship between glass–ceramic composition, process, and mechanical properties.

“…They are known for their high melting point, excellent temperature chemical stability, and high creep resistance 126 . Furthermore, they exhibit a low coefficient of expansion, low thermal conductivity, and impressive temperature creep characteristics 127,128 . As temperature increases, both the flexural strength and fracture toughness of mullite ceramics improve, a feature that has garnered considerable attention.…”

Mechanochemical synthesis is a technology formed in the 1950s. By applying mechanical energy, mechanochemical synthesis stimulates chemical reactions, causing structural and phase changes and enabling difficult or otherwise impossible reactions to occur. Mechanochemical reactions are relatively safe, clean and efficient. At present, the synthesis of oxide ceramic materials by mechanochemical methods has attracted widespread attention. In the production of oxide ceramic materials, the characteristics of ceramic powder have a certain influence on the molding, sintering, microstructure, and mechanical properties of subsequent ceramics. In this paper, the research progress of mechanical chemistry in the synthesis of nanostructures and composite oxide ceramic powders is reviewed. The effects of process parameters such as ball milling time, speed, atmosphere, grinding media, additives, and ball‐to‐powder ratio on reaction kinetics, phase formation, and powder properties are summarized. In addition, challenges and opportunities for ceramic powder synthesis are also discussed.

“…Production of refractory bricks of all sort largely depends on the diminutive preparation from its powder state prior to densification. Variety of powder production methods are employed for high temperatures refractories such astronautics, crucibles applications etc., this methods include sol gel, ultrafine ball milling [7]. Moreover, comprehensive physicochemical and mechanical properties evaluation is key to ascertaining an excellent brick [8].…”

Refractories bricks’ excellent thermomechanical and chemical resistant features makes it invaluable materials in modular incinerator ˃ 1000 °C applications. In this research, suitable physicochemical and performance evaluation were employed using X-Ray Fluorescence (XRF), dimensional property assessment, linear shrinkage and water absorption analysis. The samples were sourced from Auchi (ARB1), Afowa (ARB2), Ayogwiri (ARB3), Aviele (ARB4) and Agbede (ARB5) clay minerals deposit in Edo North, Edo State, Nigeria. Then green compact samples were fired into dense phase. The result from the XRF study revealed a generally established composition of ARB1 clay mineral of SiO2: 44.34%, Al2O3: 36.36% and others. ARB2 clay mineral of SiO2: 41.78%, Al2O3: 39.62% and others. ARB3 clay mineral of SiO2: 45.04%, Al2O3: 34.01% and others. ARB4 clay mineral of SiO2: 40.12%, Al2O3: 38.96% and others. ARB5 clay mineral of SiO2: 47.03%, Al2O3: 34.52% and others. The elemental composition of ARB1-5 revealed a similar trend of alumina and silica content to high-Al2O3 bricks (SiO2: 45.0 – 56.0%, Al2O3: 39.0 – 48.0% and others) and commercial clay bricks (SiO2: 48.0%, Al2O3: 36.96% and others) respectively. An average lower percentage error ERL, ERW, and ERH of ARB1 samples 0.148, 0.248 and 0.28% were recorded respectively. The average linear shrinkage and water absorption analysis of 9.91 and 4.71% demonstrated a potential for high elasticity of modulus. The overall data from this research shows that ARB1-5 bricks can find use in incinerator and high temperature applications.
