Munyika yekugadzira zvinhu nemazvo, kune chinhu chinotsigira budiriro yeindasitiri dzakawanda dzemhando yepamusoro - chakaoma kupfuura simbi, hachipise kupisa kupfuura graphite, asi chinogara chichichengetedza muviri wakareruka. Izvi ndizvondiro yesimbi yesilicon carbide, "chinhu chakakosha" muindasitiri yemazuva ano.
1、 Zvipo zvezvisikwa uye kuumbwa kweuchenjeri hwevanhu
Silicon carbide (SiC) haisi chigadzirwa chetsaona murabhoritari. Kare muna 1893, masayendisiti akawana chicherwa ichi chinowanikwa zvakasikwa. Mazuva ano, nekushandisa tekinoroji yekugadzira tembiricha yepamusoro kubatanidza jecha resilicon necarbon sources pakupisa kwakanyanya, zvigadzirwa zvesimbi zvesilicon carbide zvemhando yepamusoro zvinogadzirwa zviri nani. Izvi zvinosanganisa zvakakwana kugadzikana kweceramics nehunhu hwe semiconductors, zvichigadzira gene rezvinhu rakasiyana.
2, Bvisa mabhenefiti mashanu makuru
1. Muchengeti wekupisa kwakanyanya
Mumamiriro ezvinhu akaipisisa e1350 ℃, simbi dzakajairika dzakatonyorova uye dzakakanganisika, nepo maplate esimbi esilicon carbide achiri kugona kuchengetedza chimiro chayo. Kusagadzikana kwekupisa kwakanyanya uku kunoita kuti ive sarudzo yakakodzera kuminda yakaita semidziyo yekunyungudutsa uye mainjini emuchadenga.
2. Nhoo yekudzivirira yakasimba kwazvo
Kuomarara kwacho, kuri kwechipiri kune dhaimani, kunoita kuti maplate esilicon carbide akwanise kuramba kukanganiswa nekukura kwesimbi yakanyungudutswa. Pamutsetse wekugadzira aluminium, hupenyu hwayo hunowedzerwa kanopfuura kashanu kana tichienzanisa nezvinhu zvechinyakare zvinoramba kushanda.
3. Ane hunyanzvi mukufambisa kupisa
Kusiyana ne "hunhu hwekudzivirira" hwe "ceramics" dzakajairika, silicon carbide ceramics dzine thermal conductivity yakanaka kwazvo. Chinhu ichi "chinofema" chinogona kutamisa kupisa nekukurumidza uku chichichengetedza kugadzikana kwacho, zvichiita kuti chishande zvakanaka mumunda we semiconductor heat dissipation.
4. Mupiona akareruka
Nesimba rimwe chete iroro, huremu hwayo hunongova chikamu chimwe muzvitatu chesimbi. Hunhu uhwu hwe "kusimudza zvinhu zvinorema zvishoma" hunounza mhinduro dzekuvandudza kuderedza huremu kuminda yakaita semidziyo mitsva yesimba uye nzira dzekufambisa njanji.
5. Mudziviriri weMakemikari
Zvichitarisana nechinhu chinoparadza zvakanyanya, simbi dzesilicon carbide dzinoratidza kugadzikana kunoshamisa. Muchinhu chinogadzirisa makemikari, zvakaita sechinodzivirira chisingamboiti ngura, zvichiita kuti kugadzirwa kwacho kuchengetedzeke.
3, Mikana isingaperi yekuchinja ramangwana
Kubva pachikamu chinotakura mutoro chemasero emagetsi ezuva nezuva kusvika kuzvinhu zvisingapfeki zvemichina chaiyo, kubva pachigadziko chekupisa che semiconductor chips kusvika pamodule yekusefa yemidziyo yekudzivirira zvakatipoteredza, maplate esimbi esimbi esimbi esimbi esimbi esimbi ari kutsanangura patsva miganhu yekushanda kwezvinhu zveindasitiri. Muminda yehunyanzvi yakaita sesimba idzva, ruzivo rwemagetsi, uye michina yepamusoro-soro, zvinhu zvesimbi zvesimbi zvesimbi zvesimbi zvesimbi zvesimbi zviri kusimudzira indasitiri chinyararire.
Semunhu anogadzira tekinoroji anobatanidzwa zvakanyanya mubasa rezvigadzirwa zvesimbi, tinogara takazvipira kusundira mberi mashandiro ezvigadzirwa zvesimbi zvesilicon carbide zvakanyanya. Nekuvandudza maitiro ekugadzira sintering uye matekiniki ekugadzirisa pamusoro, bhodhi rega rega resimbi rinova basa rehunyanzvi rinogona kutsungirira bvunzo yenguva. Remangwana rasvika, ngationei pamwe chete runako rwakasiyana rwezvigadzirwa zvesimbi zvesilicon carbide zvichikura muminda yakawanda.
Shandong Zhongpeng inogara ichitevedzera pfungwa yekuti "kuvandudzwa kwezvinhu zvinotungamira kufambira mberi kwemaindasitiri", uye inotarisira kushanda nevatinoshanda navo pasi rose kuti vaongorore mikana isingaperi yekushandisa silicon carbide ceramics.
