CHERECHEDZA: Zviratidzo zvehunyanzvi zviri pamusoro apa zvinongomiririra chete kukosha kwakajairika kwekutarisa.
Kurongedza kwechigadzirwa: 1 kg/bhegi, kurongedza bhegi realuminium foil, 10 kg/bhokisi (zvinoenderana nekukumbira kwevatengi kuti vanyore chiratidzo)
Boron nitride ikristaro inoumbwa nemaatomu enitrogen nemaatomu eboron. Maumbirwo ekristaro akakamurwa kuita: hexagonal boron nitride (HBN), hexagonal boron nitride (WBN) uye cubic boron nitride. Pakati pawo, kristaro yehexagonal boron nitride Maumbirwo acho ane chimiro chakafanana negraphite, chinoratidza hupfu hwakareruka, hunozora, hunotora hunyoro, uye huremu hwakareruka hweupfu huchena, saka hunonziwo "white graphite". Kuwanda kwedzidziso ndeye 2.27g/cm3, simba regiravhiti chaiyo ndeye 2.43, uye kuomarara kweMohs kuri 2.
Hexagonal boron nitride ine insulation yakanaka yemagetsi, thermal conductivity. chemical stability, hapana nzvimbo yekunyunguduka iri pachena, 3000°C mu 0.1MPA nitrogen, mumhepo inoderedza kupisa, inodzivirira kupisa kusvika 2000°C, inoshandiswa munitrogen ne argon tembiricha inogona kusvika 2800°C, kugadzikana kwacho hakuna kunaka mumhepo yeokisijeni, uye tembiricha yekushandisa iri pasi pe1000°C. Expansion coefficient ye hexagonal boron nitride yakaenzana neye quartz, asi thermal conductivity yakapetwa kagumi kupfuura ye quartz. Inewo lubricity yakanaka pakupisa kwakanyanya. Imafuta akasimba ekupisa kwepamusoro ane simba rakasimba rekunyudza neutron, stable chemical properties, uye chemically inert kune dzinenge simbi dzese dzakanyungudutswa.
Hexagonal boron nitride Hainyungudike mumvura inotonhora. Kana mvura yafashaidzwa, inonyungudika zvishoma nezvishoma uye inoburitsa huwandu hushoma hwe boric acid ne ammonia. Haisangani nema acid asina simba uye mabhesi akasimba patembiricha yemumba. Inonyungudika zvishoma mu hot acid. Shandisa sodium hydroxide yakanyungudutswa uye potassium hydroxide. Kugadzira kunogona kuora. Inodzivirira ngura zvakanyanya kune akasiyana inorganic acids, alkalis, salt solutions uye organic solvents.
Nzvimbo dzakasiyana dzekushandisa dzakadai se:
| Chinhu chinoburitsa mold chinogadzirwa nesimbi uye chinozorwa pakugadzira waya | Yakakosha pasi pe electrolysis yekupisa kwakanyanya, zvinhu zvekupikisa | Inogona kushandiswa pakupisa kwakanyanya, kumanikidzwa kwakanyanya, kuputira uye zvikamu zvekupisa | Mafuta anopisa zvakanyanya anodzivirira kupfekwa anowedzera kupisa |
|
Desiccant inovhara kupisa ye transistor zvimwe zvinowedzera polymer |
Kudzivirira kupisa kwemuchadenga Zvinhu |
Mushure mekurapwa nekupisa kwakanyanya uye kumanikidzwa kwakanyanya, inogona kushandurwa kuita cubic boron nitride yakasimba sedhaimani |
Kuvaka zvinhu zveatomu reactor f |

★Mirayiridzo yekuchengetedza: Chigadzirwa ichi ndechemhando yepamusoro, hachidyike, masiki ekuchengetedza uye magirovhosi erabha zvinofanirwa kupfekwa panguva yekushanda.
Nyaya dzekuchengetedza nekufambisa:
1. Chigadzirwa ichi hachibati uye hachiputi uye chinogona kuchengetwa uye kutakurwa semakemikari akajairika.
2. Chengeta munzvimbo inotonhorera, yakaoma, kudzivirira mvura, hunyoro, uye kudzivirira kudya netsaona
