I-Boron Nitride yinto eyenziwe ngodongwe eyenziwe ngobuchule obuphezulu efumaneka kwimo eqinileyo neyomgubo. Iimpawu zayo ezikhethekileyo - ukusuka kumthamo ophezulu wobushushu kunye nokuqhuba okugqwesileyo kobushushu ukuya ekusetyenzisweni okulula, ukuthambisa, ukungaguquguquki kwe-dielectric ephantsi kunye namandla aphezulu e-dielectric - zenza i-boron nitride ibe yinto ebalaseleyo ngokwenene.
Kwimo yayo eqinileyo, i-boron nitride idla ngokubizwa ngokuba yi-"white graphite" kuba inesakhiwo esifana nese-graphite. Nangona kunjalo, ngokungafaniyo ne-graphite, i-boron nitride sisithinteli sombane esibalaseleyo esinobushushu obuphezulu be-oxidation. Inika ukuhanjiswa kobushushu obuphezulu kunye nokumelana okuhle nokutsha kobushushu kwaye inokusetyenziswa ngokulula ukuze ivale ukunyamezelana phantse kuyo nayiphi na imo. Emva kokwenziwa kwe-machining, ilungele ukusetyenziswa ngaphandle kwemisebenzi eyongezelelweyo yokulungisa ubushushu okanye yokudubula.
Kwimozulu engasebenziyo nenciphayo, i-AX05 grade yeBoron Nitride grades iya kumelana namaqondo obushushu angaphezu kwama-2,000°C. Isetyenziswa njenge-insulator xa idibana ne-tungsten kunye ne-graphite electrodes kuloo maqondo obushushu.
Zonke iintlobo zeBoron Nitride zingasetyenziswa kwiindawo ezishushu ukuya kuthi ga kwi-750°C. Ayimanzi ngenxa yeentsimbi ezininzi ezinyibilikisiweyo kunye ne-slags kwaye ingasetyenziswa xa idibene neentsimbi ezininzi ezinyibilikisiweyo kuquka i-aluminium, i-sodium, i-lithium, i-silicon, i-boron, i-tin, i-germanium, kunye ne-copper.
Iipropati zeBoron Nitride ngokubanzi
Ukuze kwenziwe iimilo eziqinileyo, ii-BN powders kunye nee-binders zicinezelwa ngobushushu kwii-billets ukuya kuthi ga kwi-490mm x 490mm x 410mm kuxinzelelo oluya kuthi ga kwi-2000 psi kunye namaqondo obushushu afikelela kwi-2000°C. Le nkqubo yenza izinto ezixineneyo nezilula ukwenziwa ngomatshini kwaye zilungele ukusetyenziswa. Ifumaneka phantse kuyo nayiphi na imilo eyenzelwe wena enokwenziwa ngomatshini kwaye ineempawu ezizodwa kunye neempawu zomzimba ezenza ukuba ibe luncedo ekusombululeni iingxaki ezinzima kwiintlobo ngeentlobo zezicelo zoshishino.
