Mechanochemical synthesis of activated Me–BN (MeAl, Mg, Ti) nanocomposites

Hallmarks of mechanochemistry: from nanoparticles to technology

“…The similar data were obtained for systems Fe-C, 473 Zr-C, 474 Ti-C, 475 TiH 2 -C, 476 Mg-C, 477 Mo-C, 478 Si-C, 479 Al-BN and Mg-BN, 480 Ti-BN 480,481 and Fe-BN. 482 General mechanisms are identical for all systems.…”

“…It was proposed that the T S decrease induced by MA is due to the ''forced'' mechanochemical wetting of graphite by Al, with partial chemical bonding of components at the surface. Similar data were obtained upon heating mechanically activated Si-C 479a and Al-BN 480 and their mixtures. In the last case two products (AlN and AlB 2 ) are simultaneously formed.…”

Formation of flower-like MgO crystal and its effect on the photoluminescence of Mg-cBN ceramics

“…Its electronic properties, dominated by a wide band gap and a relatively small dielectric constant [4][5][6][7], and the feasibility to be doped into both n-and p-type semiconductors [8] enable cBN great potential to be used as ultraviolet optic and high-temperature microelectronic materials at high power level and in a caustic environment [9,10]. For examples, cBN can be used in active and passive elements of integrated circuits, surface acoustic wave devices, various detectors, heat-conducting substrates, cold emitters, etc.…”

Deformation-induced dissolution of borides in FCC Fe–Ni alloys

“…Such boron qualities present a great interest for design of alloys containing supersaturated solid solutions of boron and disperse secondary borides on the crystallite boundaries. Moreover, boron and borides, for example, orthorhombic boron nitride, are used for the creation of layered composite materials [20][21][22]. Possibility of mechanical dissolution of borides and the formation of crystal solid solutions of boron in FCC Fe-Ni alloys by intensive cold plastic rotation deformation in Bridgman anvils is investigated in this research.…”
