Boron nitride ni idabobo itanna to dara, adaṣe igbona, iduroṣinṣin kemikali, ati pe ko si aaye yo ti o han gbangba.Iwọn lilo ti o pọju ni 0.1MPA nitrogen le de ọdọ 3000 °C, ni oju-aye didoju didoju, o le duro ooru si 2000 °C, ati iwọn otutu lilo ni nitrogen ati argon le de ọdọ 2800 °C, ati iduroṣinṣin ninu afẹfẹ atẹgun jẹ ko dara, ati iwọn otutu lilo ko kere ju 1000 °C.Olusọdipúpọ ìmúgbòòrò ti boron nitride hexagonal jẹ deede si ti quartz, ṣugbọn iṣesi igbona jẹ igba mẹwa ti quartz.
Ni afikun, hexagonal boron nitride ko ni tu ninu omi tutu, ati nigbati omi ba ti wa ni sise, hydrolysis jẹ o lọra pupọ ati pe o nmu iye kekere ti boric acid ati amonia.Ko ṣe idahun pẹlu acid alailagbara ati ipilẹ to lagbara ni iwọn otutu yara, tiotuka diẹ ninu acid gbona, ati pe o nilo lati ṣe itọju pẹlu iṣuu soda hydroxide didà ati potasiomu hydroxide lati decompose.
