Solid-state properties of hot-pressed TiB2 ceramics

Improving Hardness and Toughness of Boride Composites Based on AIMgB₁₄

“…In addition, milling under an inert atmosphere produces clean, oxide-free surfaces that have a high activity and are more readily sinterable [57]. For comparison, attempts to sinter un-milled -325 mesh TiB 2 resulted in highly porous, low-strength compacts.…”

“…In fact, the electrical conductivity of Ti metal is lower than that of its diboride [55][56]. Some of these, especially TiB 2 , also have considerable resistance to various forms of corrosion including attack from oxidation, liquid metals, and acids [55,[57][58]. Since these diborides have the same crystal structure, many of these compounds also have complete solid solubility with each other [54,[59][60].…”

Correlation Studies between Outdoor Exposure and Accelerated Laboratory Corrosion Tests for Galvanic and Non-Galvanic Ceramic-Aluminum Couples

“…The three major subdivisions are Non-oxide ceramics such as borides, carbides, nitrides have high strength and good oxidation resistance [10]. In this research, experiments were conducted to study the compatibilities between different non-oxide ceramics in contact with metals in corrosive environments.…”

“…The diboride studied in this research is TiB 2 . In the titanium-boron binary system, TiB 2 is the stable compound [9] and it has attractive properties such as high hardness, high melting point, excellent thermal conductivity and electrical conductivity [10]. These properties are used in a wide range of applications.…”

“…The electrical resistivity of TiB 2 varies from 9 µΩ-cm to 20 µΩ-cm [10, 24, and 25] which is about 6 times higher than the electrical resistivity of copper. Complex shapes of TiB 2 can be achieved using electric discharge machining (EDM) due to their low electrical resistivity [10,26]. TiB 2 is also used as evaporation boats due to its excellent electrical conductivity and high melting point [10,26].…”
