Powder Preparation, Properties and Industrial Applications of Hexagonal Boron Nitride

Abstract

Additional information is available at the end of the chapter http://dx.doi.org/10.5772/53325 1. Direct nitridation of boron according to 2B + N 2 = 2BNreaction. This method is limited since pure boron is an expensive element and nitridation of the element is not homogeneous even at high temperatures [2].

Additive Manufacturing of Dense Hexagonal Boron Nitride Objects

“…The average value on the surface perpendicular to the axis of the disks was 0.14±0.01 GPa, while that of the surface parallel to the axis was 0.17±0.01 GPa. These Vickers hardness values are comparable to values reported for dense sintered boron nitride, which are in the range between 0.15 and 0.24 GPa [9] and demonstrate the high degree of densification achieved. At the time of writing this report, sintering of crucibles had not been completed.…”

Mechanical and thermal properties of wood‐plastic composites reinforced with hexagonal boron nitride

“…The h‐BN may act as electrical current barriers to prevent the formation of an electrically conductive network in the composite . It has strong chemical and thermal stability, low thermal expansion, easily machined nonabrasive and lubricious, low reactivity with metals, easy machinability, excellent thermal shock resistance, improved the wear resistance of polymers and non toxic . Apart from carbon nanotubes, silica, alumina, aluminum nitride, zinc oxide, and organoclay, the h‐BN is a soft, lubricious material that can be compounded into plastics with minimal impact on processing equipment .…”

Gamma Attenuation Behavior of h-BN and h-BN-TiB2Composites

“…There are also some applications in nuclear technology such as in neutron detectors and neutron shielding applications [4]. There are some studies related with h-BN which commonly were studied on neutron properties [5].…”
