Silicon Carbide Crucible: Guhitamo Ibyiza byo gushonga ibyuma

Mu rwego rwo gutunganya ibyuma na metallurgie,silicon karbide yabambwebyagaragaye nkibikoresho byingirakamaro, byamamaye kubikorwa byiza kandi biramba. Kwinjiza umusaraba wa silicon karbide byongereye cyane imikorere nubuziranenge bwibikorwa byo gushonga ibyuma. Izi mbuto zizwi cyane kubintu byihariye bidasanzwe, bibafasha guhangana nubushyuhe bwo hejuru no kurwanya ruswa, bigatuma imikorere ihamye ndetse no mubidukikije bikabije.

Ibiti bya silicon karbide bikozwe mubikoresho byiza bya silicon karbide, bizwiho gukomera bidasanzwe hamwe nubushyuhe bwumuriro. Iyi miterere yemeza ko igikomeye kigumana ubusugire bwimiterere nubwo haba hari ubushyuhe bukabije bwo gushonga ibyuma. Bitandukanye na gakondo ya grafite, umusaraba wa silicon karbide wirata ubuzima burebure. Ntibishobora guhinduka mugihe cyogukoresha kandi birwanya guhangana nibyuma byashongeshejwe, nibyingenzi mukubungabunga isuku yicyuma gishongeshejwe.

Kimwe mu bintu bigaragara biranga silikoni ya karbide ni ukurwanya ubushyuhe bwinshi. Barashobora kwihanganira ibyifuzo bikenerwa byo gushonga ibyuma, akenshi bikubiyemo ubushyuhe bugera kuri dogere selisiyusi ibihumbi. Byongeye kandi, izo mbuto zigaragaza imbaraga zidasanzwe zo kwangirika kw’imiti, bigatuma zishobora kutagira ingaruka ku bidukikije bikabije by’imiti bikunze kugaragara mu gihe cyo gushonga ibyuma. Iyi myigaragambyo yemeza ko umusaraba ukomeza gukora neza mugihe kinini.

Iyindi nyungu ikomeye ya silicon karbide yabambwe ni coefficient nkeya yo kwagura ubushyuhe. Ibi biranga kugabanya ibyago byo guturika mugihe cyo gushyushya byihuse no gukonjesha, ibintu bikunze kugaragara mugushonga ibyuma no gutara. Ubushobozi bwo guhangana niyi mikorere yubushyuhe butuma umusemburo wa karubide ya silikoni ikenerwa cyane cyane kubisabwa nko gukora ibyuma no gukora amavuta. Haba muri laboratoire hagamijwe ubushakashatsi cyangwa mu nganda nini nini mu nganda, umusemburo wa kariside ya silicon uhora uhuza ibikenerwa bitandukanye byo gutunganya ibyuma.

Ubwinshi nubwizerwe bwa silicon karbide yabambwe byatumye abantu benshi bamenyekana muburyo butandukanye. Mu bushakashatsi bwa laboratoire, butanga uburyo bunoze bwo gushonga, bigafasha abahanga gukora ubushakashatsi hamwe nukuri. Mu nganda, igihe kirekire no gukora bigira uruhare mu kongera umusaruro no kugabanya ibiciro byakazi.

Muri make,silicon karbide irakomeyes bigenda bisimbuza buhoro buhoro umusaraba gakondo, bihinduka ihitamo ryinganda zigezweho za metallurgjiya kubera imikorere myiza yabo hamwe nuburyo bugaragara bwo gukoresha. Mugihe ikoranabuhanga rikomeje gutera imbere, biteganijwe ko umusaraba wa silicon karbide uzagira uruhare runini mugihe kizaza cyinganda zitunganya ibyuma. Ubushobozi bwabo bwo kwihanganira ibihe bikabije, hamwe no kuramba kwabo no kwizerwa, kubashyira muburyo bwiza bwo guhitamo ibyuma.
