EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

Advanced ceramics (made up of oxides, nitrate compounds, carbides and non-silicate glass) present interesting properties, among others, as thermal insulation, lightness, high specific surface area, thermal shock resistance, mechanical strength or chemical inertness. Consequently, the development of ceramics for high temperature applications has become an emerging area of research. These...

Lithium aluminum silicate (LAS) system is frequently used in many fields of applications due to its low or even negative coefficient of thermal expansion, good thermal shock resistance, high thermal stability, and high chemical durability. However, materials with negative CTE often have low fracture strength because the expansion anisotropy causes microcracking. In order to improve its...

Nowadays, many industrial applications demand the use of components working under extreme conditions, particularly very high temperatures for long times. For this kind of applications properties such as low thermal conductivity, low thermal expansion coefficient and high chemical resistance are strongly required. Advanced ceramics, such as zircon and zirconia, have similar coefficient of...
