Boron nitride ikristaro inoumbwa nemaatomu enitrogen nemaatomu eboron. Chimiro chekristaro chakakamurwa kuita hexagonal boron nitride (HBN), yakazara yakazara hexagonal boron nitride (WBN) uye cubic boron nitride. Iyo crystal chimiro chehexagonal boron nitride ine yakafanana graphite-yakafanana chimiro, inoratidzira yakasununguka, yakarongedzwa, nyore kunyura hunyoro, huremu huremu uye mamwe mavara eupfu chena, saka inonziwo "white graphite".
Theoretical density 2.27g/cm3, chaiyo giravhiti: 2.43, Mo kuomarara 2.
Hexagonal boron nitriding ine magetsi ekudzivirira zvakanaka, kupisa kwekushisa, kugadzikana kwemakemikari, pasina kunyunguduka kuri pachena, kupisa kwekushisa mu 0.1MPA nitrogen kusvika 3000ºC, mumhepo inoderedza kusina kwaakarerekera, kupisa kupisa kusvika 2000ºC, nitrogen uye argon mukushandiswa kwekushisa kunogona kusvika 2800ºC, muokisijeni mumhepo kugadzikana kwakashata, kushandiswa kwekushisa kuri pasi pe1000ºC.
Hexagonal boron nitride ine yakaenzana yekuwedzera coefficient sequartz, asi kupisa kwayo kupeta kagumi kune yequartz. Iyo zvakare ine lubricity yakanaka pakupisa kwepamusoro, inoyevedza yakakwira tembiricha yakasimba lubricant, ine yakasimba neutron absorption kugona, kugadzikana kwemakemikari, uye ine makemikari inert kune angangoita ese masimbi akanyungudutswa.
Hexagonal boron nitriding insoluble mvura inotonhora, mvura inofashaira hydrolysis inononoka uye inoburitsa shoma shoma yeboric acid uye ammonia, uye isina kusimba asidhi uye yakasimba hwaro pakupisa kwekamuri hauite, kunyungudika zvishoma muasidhi inopisa, ine yakanyungudutswa sodium hydroxide, potassium hydroxide. kurapwa kuora. Iyo ine yakakura corrosion kuramba kune akasiyana inorganic acids, mabhesi, munyu mhinduro uye organic zvinonyungudutsa.

Hexagonal boron nitride imhando yemhando yepamusoro ceramic zvinhu. Iyo microstructure yayo haina kujeka uye chimiro chayo chemolecular is hexagonal crystal. Hexagonal boron nitride ine yakasarudzika uye yakanakisa yemuviri nemakemikari zvivakwa. Iyo ine yakanaka kwazvo yekupisa conductivity, magetsi ekudzivirira, makemikari ekuora kwekudzivirira uye oxidation kuramba. Inogona kumira kusvika ku1000OC mumhepo, uye kusvika ku2000OC muinert gasi uye vacuum. Iyo crystalline boron nitride yakanyungudutswa pakupisa kukuru kwe2000OC, ine makemikari akagadzikana uye emuviri zvimiro uye yakanakisa yekupisa conductivity (iyo yekupisa conductivity yekristaro imwechete inenge 250-300W/mk). Parizvino, kambani inogadzira flake crystalline poda ine saizi imwe chete yekristaro ye500 nanometer-20 microns uye nanoscale spherical boron nitride.
Hexagonal boron nitride inofarirwa neindasitiri yemagetsi nekuda kweiyo isingawanzo mamiriro ekukwirira kwekushisa conductivity uye kushanda kwemagetsi ekudzivirira. Vagadziri vemagetsi epamba nekunze vakaita tsvakiridzo yakakura-yekushandisa mumapurasitiki anopisa, semiconductor packaging uye kuzadza, LED kupisa disipaging packaging, etc. Iine hunyanzvi hwekuita mune imwe tsika yechinyakare kunyungudutsa simbi, kukanda, yakakosha mafuta ekuzora, indasitiri yegirazi uye imwe boron. nitride industries.
Mamwe maindasitiri anowanzo batsirwa nehexagonal boron nitride ceramics anosanganisira:
● Muchadenga
● Kugadzira simbi
● Zvemagetsi
● Kudziisa uye Kutonhodza
● Kugadzirwa kwegirazi
● Mauto uye Dziviriro
