  • Boron Nitride
    . Depending on the purity, density and crystal structure, boron nitride is used for refractory linings, industrial crucibles, arc furnace electrodes, analytical labware, composites, refractory cements and super abrasives. Hexagonal BN is structurally weak and used as a high temperature lubricant
  • MICRO: Special Apps
    . The ability to produce high-performance circuits using SiC without significant new investment in cutting-edge fabrication tools is particularly appealing. Table I compares several wide-band-gap materials to silicon. Gallium nitride (GaN) has good mobilities but is hampered by low thermal conductivity
  • Ceramic-Matrix Composites
    materials being used for such interfaces are boron nitride and carbon, materials that have weak crystallographic orientations that preferentially delaminate. Modifications to the interfacial zone of whisker-reinforced composites are in their developmental infancy because of the difficulty
