Editing Boron nitride (section)

====Thermal stability====
The air stability of graphene shows a clear thickness dependence: monolayer graphene is reactive to oxygen at 250&nbsp;°C, strongly doped at 300&nbsp;°C, and etched at 450&nbsp;°C; in contrast, bulk graphite is not oxidized until 800&nbsp;°C.<ref name="LiSantos2014"/> Atomically thin boron nitride has much better oxidation resistance than graphene. Monolayer boron nitride is not oxidized till 700&nbsp;°C and can sustain up to 850&nbsp;°C in air; bilayer and trilayer boron nitride nanosheets have slightly higher oxidation starting temperatures.<ref name="LiCervenka2014">{{cite journal|last1=Li|first1=Lu Hua|last2=Cervenka|first2=Jiri|last3=Watanabe|first3=Kenji|last4=Taniguchi|first4=Takashi|last5=Chen|first5=Ying|title=Strong Oxidation Resistance of Atomically Thin Boron Nitride Nanosheets|journal=ACS Nano|volume=8|issue=2|year=2014|pages=1457–1462|doi=10.1021/nn500059s|pmid=24400990|arxiv=1403.1002|bibcode=2014arXiv1403.1002L|s2cid=5372545}}</ref> The excellent thermal stability, high impermeability to gas and liquid, and electrical insulation make atomically thin boron nitride potential coating materials for preventing surface oxidation and corrosion of metals<ref name="LiXing2014">{{cite journal|last1=Li|first1=Lu Hua|last2=Xing|first2=Tan|last3=Chen|first3=Ying|last4=Jones|first4=Rob|title=Nanosheets: Boron Nitride Nanosheets for Metal Protection (Adv.
