“…The observed sensitivity to moisture after the deposition has been reported earlier for BN films synthesized by both CVD and PECVD, especially for amorphous films and films of low crystalline quality [5,19,20,21,22]. The fact that the films deposited in this study show similar sensitivity towards moisture again suggests that they are amorphous BN films.…”

On the effect of water and oxygen in chemical vapor deposition of boron nitride

close to stoichiometric, although containing a few atomic percent oxygen and hydrogen, Xray diffraction measurements show no indications for nucleation of any crystalline BN phases, despite change in N/B-ratio and/or process temperature. Thermodynamic modeling suggests that this is due to formation of strong B-O bonds already in the gas phase in the presence of water or oxygen during growth. This growth behavior is believed to be caused by an uncontrolled release of water and/or oxygen in the deposition chamber and highlights the sensitivity of the BN CVD process towards oxygen and water.

“…[1][2][3] While structurally similar to graphite and graphene, h-BN has a distinct set of complementary and, in many cases, advantageous properties compared to its and environmental protection. Research efforts have focused on porous alumina supports, [29][30][31] which suffer from low thermal conductivity, and thin fi lms of catalytic metals, [ 30,[32][33][34] which have low active surface area.…”

A high‐surface‐area, highly crystalline boron nitride aerogel synthesized with nonhazardous reactants has been loaded with crystalline platinum nanoparticles to form a novel nanomaterial that exhibits many advantages for use in a catalytic gas sensing application. The platinum nanoparticle‐loaded boron nitride aerogel integrated onto a microheater platform allows for calorimetric propane detection. The boron nitride aerogel exhibits thermal stability up to 900 °C and supports disperse platinum nanoparticles, with no sintering observed after 24 h of high‐temperature testing. The high thermal conductivity and low density of the boron nitride aerogel result in an order of magnitude faster response and recovery times (<2 s) than reported on alumina support and allow for 10% duty cycling of the microheater with no loss in sensitivity. The resulting 1.5 mW sensor power consumption is two orders of magnitude less than commercially available catalytic gas sensors and unlocks the potential for wireless, battery‐powered catalytic gas sensing.

Preceramic polymers to boron nitride (BN) have been synthesized by thermal condensation of different (alkylamino)borazine monomers. Crystalline BN was obtained by pyrolysis of those polymeric precursors in NH 3 and then in Ar. The influence of monomer structure on the chemical composition, microstructure, oxidation resistance and high temperature stability of BN was investigated by a combination of elemental analysis (EA), density measurement, FTIR, XPS, XRD, HRTEM and TGA. With similar chemical composition, BN derived from symmetric monomer exhibited a higher crystallinity, better oxidation resistance and higher temperature stability. This was because that the structure of the precursor polymerized from symmetric molecular was close to that of hexagonal BN (h-BN).
