Silicon nitride yomangidwa ndi silicon carbide
Si3N4 yomangidwa ndi SiC ceramic refractory material, imasakanizidwa ndi ufa wapamwamba kwambiri wa SIC ndi Silicon ufa, pambuyo poponyera njira, zomwe zimapangidwira pansi pa 1400 ~ 1500 ° C.Pa nthawi ya sintering, kudzaza nayitrogeni mkulu koyera mu ng'anjo, ndiye pakachitsulo amachitira ndi Nayitrogeni ndi kupanga Si3N4, Choncho Si3N4 bonded SiC zinthu wapangidwa silicon nitride (23%) ndi silicon carbide (75%) monga zopangira zazikulu. , kusakaniza ndi zinthu organic, ndi zoumbidwa ndi osakaniza, extrusion kapena kuthira, ndiye anapanga pambuyo kuyanika ndi nitrogenization.
Mbali ndi ubwino:
1.High kutentha kulolerana
2.High matenthedwe conductivity ndi kukaniza mantha
3.Mkulu wamakina mphamvu ndi kukana abrasion
4.Kupambana kwamphamvu kwamphamvu komanso kukana dzimbiri
Timapereka zida za ceramic zamtundu wapamwamba kwambiri komanso zolondola kwambiri za NSiC zomwe zimayendetsedwa ndi
1.Slip casting
2.Kutulutsa
3.Uni Axial Pressing
4.Isostatic Pressing

WeiTai Energy Technology Co., Ltd. ndi katundu wotsogola wa zoumba zapamwamba semiconductor ndi wopanga yekha ku China amene nthawi imodzi kupereka mkulu-chiyero pakachitsulo carbide ceramic (makamaka Recrystallized SiC) ndi CVD SiC ❖ kuyanika.Kuphatikiza apo, kampani yathu idadziperekanso ku minda ya ceramic monga aluminiyamu nitride, zirconia, ndi silicon nitride, etc.
Zogulitsa zathu zazikulu kuphatikiza: silicon carbide etching disc, silicon carbide boat tow, silicon carbide wafer boat (Photovoltaic & Semiconductor), silicon carbide ng'anjo chubu, silicon carbide cantilever paddle, silicon carbide chucks, silicon carbide mtengo, komanso zokutira CVD SiC ndi TaC zokutira.Zogulitsa zomwe zimagwiritsidwa ntchito makamaka m'mafakitale a semiconductor ndi photovoltaic, monga zida zakukula kwa kristalo, epitaxy, etching, ma CD, zokutira ndi ng'anjo zoyatsira, etc.
Kampani yathu ili ndi zida zonse zopangira monga kuumba, sintering, processing, zida zokutira, ndi zina zambiri, zomwe zimatha kumaliza maulalo onse ofunikira pakupanga zinthu ndikukhala ndi kuwongolera kwakukulu kwazinthu;Ndondomeko yoyenera yopangira ikhoza kusankhidwa malinga ndi zosowa za mankhwala, zomwe zimapangitsa kuti pakhale mtengo wotsika komanso kupereka makasitomala zinthu zopikisana kwambiri;Titha kusinthasintha komanso moyenera kukonza kupanga kutengera zofunikira pakubweretsa komanso molumikizana ndi machitidwe owongolera madongosolo a pa intaneti, kupatsa makasitomala nthawi yachangu komanso yotsimikizika yobweretsera.
