Boron nitride finds new applications in thermoplastic compounds

Facile synthesis of hexagonal boron nitride nanoplates via molten-salt-mediated magnesiothermic reduction

“…h-BN has been used in ceramic matrix composites for decreasing the thermal expansion coefficient, enhancing thermal shock resistance of the composite and improving machinability [5][6][7]. Moreover, h-BN has also been used in polymer matrix composites to improve the flame retardancy and toughness properties [8,9]. In comparison to the carbon system, BN is a semiconductor with a wide band gap near 6 eV [4,10], which makes h-BN a promising candidate for deep-blue and UV applications [11].…”

Investigation of ceramic boron nitride by terahertz time-domain spectroscopy

“…The electrical insulating character and thermal conductivity of BN make it valuable as an additive in thermal interface greases and pads for cooling electronic devices. 10 Addition of BN powder to matrices, be they metal, ceramic, or polymer, usually results in a weakening of the matrix at a critical concentration. This aspect of BN is used in thermally sprayed abradable coatings for aircraft engine housings, where coatings comprised of BN and metals allow turbine blades to smear the housing coating and maintain a close tolerance between the blade tip and the housing, which translates into improved engine efficiencies.…”

Preparation and characterization of hexagonal boron nitride and PAMPS-NMPA-based thin composite films and investigation of their membrane properties

“…For this purpose, inorganic materials such as SiO 2 , TiO 2 , graphene, and carbon nanotube have been used for the development of novel composite membranes due to their good mechanical, thermal, and chemical stability [12][13][14][15][16]. Hexagonal boron nitride (hBN) is the isoelectric analogue of graphite and is the most desired polymorph among other boron nitrides.…”

“…Recently, the development of polymer composites containing nanoscaled filler has become a popular topic in materials science [13,15,18,20,[23][24][25]. The employing of hBN in polymers is mainly based on its thermal conductivity property [18][19][20][21].…”
