Boron nitride CAS 10043-11-5
Boron nitride ikristaro inoumbwa nemaatomu enitrogen nemaatomu eboron. Chimiro chekristaro chakakamurwa kuita hexagonal boron nitride (HBN), pedyo-yakazara hexagonal boron nitride (WBN) uye cubic boron nitride. Iyo yekristaro chimiro chehexagonal boron nitride ine yakafanana graphite layered chimiro, ichiratidzira yakasununguka, yakarongedzwa, inobvisa unyoro, chena hupfu, saka inonziwo "white graphite". Iyo yekuwedzera coefficient ye hexagonal boron nitride yakaenzana ne quartz, asi iyo inopisa inopeta kagumi iyo yequartz. Iyo zvakare ine lubricity yakanaka pakudziya kwepamusoro uye ndeye yakanakisa-tembiricha yakasimba mafuta ekuzora ine simba rekutora neutron, kugadzikana kwemakemikari zvimiro, uye kusagadzikana kwemakemikari kune angangoita ese masimbi akanyungudutswa. Hexagonal boron nitride hainyunguriki mumvura inotonhora. Kana mvura ikafashaidzwa, inoita hydrolyze zvishoma nezvishoma uye inogadzira zvishoma boric acid uye ammonia. Izvo hazviiti neasina simba acids uye mabhesi akasimba pakupisa kwekamuri. Inonyungudika zvishoma muasidhi inopisa uye inogona kuparara chete nekurapa neyakanyungudutswa sodium hydroxide uye potassium hydroxide. Iyo ine huturu hwekurasika kune akasiyana inorganic acids, alkalis, munyu mhinduro uye organic zvinonyungudutsa.

1. Boron nitride inoshandiswa kugadzira zvinhu zvinoramba, zvimisikidzo zvesimbi, uye inoshandiswawo mumagetsi, muchina, ndege uye mamwe maindasitiri.
2. Boron nitride ine zvinhu zvakawanda zvakanakisa uye inoshandiswa zvakanyanya muma insulators emagetsi akakwira-voltage uye akakwira-frequency magetsi uye plasma arcs, coatings for automatic welding high-temperature resistant frames, materials for high-frequency induction furnaces, solid phase admixtures for semiconductors. , zvimiro zveatomu reactor, kurongedza zvinhu kudzivirira neutron radiation, radar kutamisa mahwindo, radar antenna midhiya uye roketi injini zvikamu. Nekuda kweiyo yakanakisa yekuzora zvivakwa, inoshandiswa seyepamusoro-tembiricha lubricant uye demoulding agent yemhando dzakasiyana. Yakaumbwa boron nitride inogona kushandiswa kugadzira yakakwirira-kupisa inodzivirira crucibles uye zvimwe zvigadzirwa. Inogona kushandiswa sechinhu chakanyanya kuoma, chakakodzera kuongorora geological, mabheti ekuchera mafuta uye maturusi ekucheka zvakanyanya. Inogona zvakare kushandiswa sesimbi yekugadzirisa kugaya zvinhu, ine hunhu hwekudzika kwekushisa kwepamusoro tembiricha uye kushomeka kwepamusoro kwezvikamu. Boron nitride inogona zvakare kushandiswa sechinhu chinowedzera kune zvakasiyana zvinhu. Boron nitride fiber inogadzirwa kubva ku boron nitride ndeyepakati-modulus yakakwirira-inoshanda faibha. Iyo inorganic synthetic engineering zvinhu zvinogona kushandiswa zvakanyanya muindasitiri yemakemikari, machira indasitiri, aerospace tekinoroji uye mamwe ekucheka-kumucheto maindasitiri zvikamu.
3.Release agent yesimbi inogadzira uye lubricant yesimbi wire dhizaini; yakakosha electrolytic uye kupikisa zvinhu pasi pekushisa kwepamusoro; lubricant yakasimba; kupisa seal desiccant kune transistors uye kuwedzera kune mapolymers akadai sepurasitiki resins; boron nitride zvigadzirwa zvakatsikirirwa mumhando dzakasiyana-siyana zvinogona kushandiswa seyepamusoro tembiricha, kudzvanywa kwakanyanya, kuvharisa uye kupisa kupisa zvikamu; Thermal shielding materials in the aerospace industry; nekutora chikamu kwezvinokonzeresa, inogona kushandurwa kuita cubic boron nitride yakaoma sedhaimondi mushure mekupisa kwakanyanya uye kurapwa kwakanyanya.
