Structural ceramics

Magnetic slip casting for dense and textured ceramics: A review of current achievements and issues

“…Those processes are tape casting [1], slip casting [2], freeze casting [3], gel casting [4] and recently, 3 dimensional (3D) printing (Figure 1A) [5]. One of the major challenges that this research tackles is the reduction of flaws that control the minimum stress to fracture following Griffith's criterion [6]. In addition, the optimization of chemical formulations and of their processes could generate ceramics with unique structural and functional properties, such as shape-memory and ductility [7,8], transparency [9], high capacity [10], biocompatibility [11], etc.…”

Corrosion characteristics of silicon carbide and silicon nitride

“…Characteristics such as high maximum use temperature, strength retention at high temperature, and chemical stability have held forth tantalizing possibilities [2,3] for more efficient engines [4], heat exchangers and recuperators [5,6] and for more durable electronic packaging [7] and chemical processing components [8]. The primary barriers that have impeded [9] the widespread development of these applications have been the susceptibility of structural ceramics to brittle fracture [10] and environmentally sensitive corrosion behavior [11], including the subsequent effects of corrosion on the thermal and mechanical performance of ceramics. The former barrier has received, by far, the greater amount of attention [12].…”

Measurement of Interfacial Tension in Liquid−Liquid High-Temperature Systems

“…This includes phenomena in catalysis, in colloid chemistry, and more generally in interfacial thermodynamics and electrochemistry. The interfacial phenomena play an important role in a number of metallurgical, pyrochemical, and other high-temperature industrial processes, such as, in aluminum, magnesium, copper, iron, and steel production (in production of primary metal per se, as well as in refining and casting), in the glass industry, in fuel cells, in molten salt oxidation processes, in the silicon industry, in pyrochemical reprocessing of spent nuclear fuel, in welding, in galvanic metallization, in corrosion, and in ceramic and other material technology (see refs to ).…”
