Boron Nitride ndeye advanced synthetic ceramic material inowanikwa yakasimba uye hupfu fomu.Hunhu hwayo hwakasiyana - kubva pakupisa kwakawanda uye kutaridzika kwemafuta ekudziya kusvika kune nyore machinability, lubricity, yakaderera dielectric inogara uye yepamusoro dielectric simba - ita kuti boron nitride ive yakasarudzika zvinhu.
Muchimiro chayo chakasimba, boron nitride inowanzonzi "white graphite" nekuti ine microstructure yakafanana neye graphite.Nekudaro, kusiyana negraphite, boron nitride insulator yemagetsi yakanakisa ine tembiricha yepamusoro oxidation.Iyo inopa yakakwira yekupisa conductivity uye yakanaka yekupisa kuvhundutsa kuramba uye inogona kugadzirwa nyore nyore kuvhara kushivirira mune chero chimiro.Mushure mekugadzira, yakagadzirira kushandiswa pasina kuwedzera kupisa kupisa kana kupfura mabasa.
Mune inert uye kudzikisira mamiriro ekunze, iyo AX05 giredhi yeBoron Nitride mamakisi inoshingirira tembiricha inodarika 2,000°C.Iyo inowanzoshandiswa se insulator inosangana ne tungsten uye graphite electrodes pane izvo tembiricha.
Ese magiredhi eBoron Nitride anogona kushandiswa muoxidizing atmospheres kusvika 750°C.Haina kunyorova nesimbi zhinji dzakanyungudutswa uye slags uye inogona kushandiswa mukusangana neakawanda masimbi akanyungudutswa anosanganisira aluminium, sodium, lithium, silicon, boron, tin, germanium, uye mhangura.
General Boron Nitride Properties
Kugadzira maumbirwo akasimba, BN hupfu nemabhainda zvinodzvanywa mumabhiridha anosvika 490mm x 490mm x 410mm pakumanikidzwa kusvika 2000 psi uye tembiricha inosvika 2000°C.Iyi nzira inoumba chinhu chakakora uye chiri nyore kugadzirwa uye chakagadzirira kushandisa.Inowanikwa mune chero chimiro chetsika chinogona kugadzirwa uye chine hunhu hwakasiyana uye zvimiro zvemuviri izvo zvinoita kuti ive yakakosha pakugadzirisa matambudziko akaomarara mune dzakasiyana siyana maindasitiri ekushandisa.
