Boron nitride ke kristale e entsoeng ka liathomo tsa nitrogen le liathomo tsa boron. Sebopeho sa kristale se arotsoe ka: hexagonal boron nitride (HBN), e haufi-ufi-packed hexagonal boron nitride (WBN) le cubic boron nitride, eo har'a eona likristale tsa hexagonal boron nitride Sebopeho se na le sebopeho se tšoanang sa graphite, se bontšang phofo e tšoeu e hlephileng. , e tlotsitsoeng, e bonolo ho monya mongobo, le boima bo bobebe, kahoo e boetse e bitsoa "graphite e tšoeu".

Theory density ke 2.27g/cm3, khoheli e khethehileng ke 2.43, 'me boima ba Mohs ke 2.

Hexagonal boron nitride e na le insulation e ntle ea motlakase, conductivity ea mocheso, botsitso ba lik'hemik'hale, ha ho na ntlha e hlakileng ea ho qhibiliha, ho hanyetsa mocheso ho 3000 ℃ ho 0.1 ℃ ho 2000MPA nitrogen, ho hanyetsa mocheso ho 2800 ℃ sebakeng sa ho fokotsa ho se nke lehlakore, ho naetrojene le Thecheso e sebetsang ho argon e ka fihla. 1000 ℃, 'me botsitso ba sepakapaka sa oksijene bo bobe,' me mocheso oa ts'ebetso o ka tlase ho XNUMX ℃.

Katoloso ea coefficient ea hexagonal boron nitride e lekana le ea quartz, empa conductivity ea mocheso e imena habeli ea quartz. E boetse e na le lubricity e ntle mochesong o phahameng. Ke setlolo se tiileng sa mocheso o phahameng se nang le bokhoni bo matla ba ho monya neutron, thepa ea lik'hemik'hale e tsitsitseng, le ho se sebetse ha lik'hemik'hale hoo e ka bang litšepe tsohle tse qhibilihisitsoeng.

Hexagonal boron nitride ha e qhibilihe metsing a batang. Ha metsi a phehiloe, a hydrolyzes butle haholo 'me a hlahisa palo e nyenyane ea boric acid le ammonia. Ha e sebetsane le li-acid tse fokolang le metheo e matla mocheso oa kamore. E qhibiliha hanyane ka har'a asiti e chesang. Sebelisa sodium hydroxide e qhibilihisitsoeng, potassium hydroxide process ho bola. E na le bokhoni bo bongata ba ho thibela kutu ho li-acid tse fapaneng tsa inorganic, alkalis, litharollo tsa letsoai le metsoako ea manyolo.
