Zvivakwa zverecrystallized silicon carbide
Recrystallized silicon carbide (R-SiC) ndeyepamusoro-inoshanda zvinhu nekuoma kwechipiri kune diamond chete, iyo inoumbwa pakupisa kwakanyanya pamusoro pe2000 ℃. Iyo inochengeta akawanda akanakisa zvimiro zveSiC, senge tembiricha yakakwira simba, yakasimba corrosion resistance, yakanakisa oxidation kuramba, yakanaka thermal shock resistance uye zvichingodaro.
● Yakanakisa michina zvinhu. Recrystallized silicon carbide ine simba repamusoro uye kuomarara kupfuura kabhoni fiber, yakanyanya kupikisa kuramba, inogona kutamba kuita kwakanaka munzvimbo dzakanyanyisa tembiricha, inogona kutamba zvirinani kuenzanisa kuita mumamiriro akasiyana siyana. Mukuwedzera, inewo kushanduka kwakanaka uye haisi nyore kukuvadzwa nekutambanudza uye kupfugama, iyo inovandudza zvikuru kushanda kwayo.
● High corrosion resistance. Recrystallized silicon carbide ine high corrosion resistance kune zvakasiyana-siyana zvezvinobudisa nhau, zvinogona kudzivirira kuparara kwemarudzi akasiyana-siyana emagetsi, inogona kuchengetedza maitiro ayo emagetsi kwenguva yakareba, ine kunamatira kwakasimba, kuitira kuti ive nehupenyu hurefu hwebasa. Uye zvakare, ine zvakare yakanaka yekudziya kugadzikana, inogona kuchinjika kune humwe huwandu hwekuchinja kwekushisa, kuvandudza kushanda kwayo kwekushandisa.
● Sintering haidzike. Nekuti iyo sintering process haidzike, hapana kusara kunetseka kunokonzeresa deformation kana kuputika kwechigadzirwa, uye zvikamu zvine maumbirwo akaomarara uye yakanyanya kurongeka inogona kugadzirwa.

VET Energy ndizvo themugadziri chaiye weakagadziridzwa graphite uye silicon carbide zvigadzirwa neCVD coating,anogona kupazvakasiyana-siyanazvakagadzirirwa zvikamu zve semiconductor uye photovoltaic indasitiri. Our tekinoroji timu inobva kumatunhu epamusoro ekutsvagisa dzimba, inogona kupa mamwe hunyanzvi zvinhu mhindurozvako.
Isu tinoramba tichigadzira advanced process kuti tipe zvimwe zvepamberi zvinhu,uyevakagadzira yakasarudzika tekinoroji ine patent, iyo inogona kuita kuti chisungo pakati pekupotera neiyo substrate ive yakasimba uye isinganyanye kubatwa.
