O le auala gaosi oloa o le tali-sintered silicon carbide o le aumaia lea o le oneone quartz sili ona lelei ma le suauʻu calcined coke i totonu o se ogaumu faʻavevela eletise. O poloka silicon carbide ua fa'amamaina e fai ma 'oloa fa'atasi ai ma le tele o vaega fa'asoa e ala i le tu'imomomoina, fa'amama malosi fa'amaneta ma alkali, mea fa'amama maneta ma su'esu'ega po'o le vavaeeseina o vai.
Silicon carbide e lua ituaiga masani masani o le kasa silicon carbide ma lanu meamata carbide, o ia mea uma e patino ile α-SiC. ① Black silicon carbide e aofia ai le 95% SiC, ma o lona ductility e maualuga atu nai lo carbide silicon lanumeamata, o le tele o ia mea e faʻaaogaina e gaosia ma faʻaogaina mea mataʻutia ma le maualalo o le malosi, e pei o tioata laminated, porcelain, maʻa, refractory, uʻamea puaa ma metala taua. ② Green silicon carbide o loʻo i ai le SiC e uiga i le 97% i luga, e lelei le faʻamaʻaina o le tagata lava ia, o le tele o ia mea e faʻaaogaina mo le gaosiga ma le gaosiga o meafaigaluega carbide, titanium metal ma tioata mata, ma e faʻaaogaina foi mo le faʻaogaina o le paʻu paʻu ma le faʻalelei maualuga-saoasaoa. meafaigaluega uamea. E le gata i lea, o loʻo i ai mita kupita o le silicon carbide, o se tioata lanumeamata lanumeamata e faia i se faiga fou, ma e faʻaaogaina e gaosia ai se faʻataʻitaʻiga talafeagai mo le faʻauluina o le super-finishing, lea e mafai ona faʻafefe ai le luga mai le Ra32 ~ 0.16μm se gaioiga. ia Ra0.04 ~ 0.02μm.
Fa'aoga autu ole fa'a'a'ai sintering silicon carbide
(1) I le avea ai o se mea e faʻafefeteina, e mafai ona faʻaaogaina e pei o se paʻu, e pei o le uili oneone, maʻa faʻamaʻa, uili uila, oneone oneone, ma isi.
(2) I le avea ai o se sui deoxidizing ma mea corrosion tetee mo alamanuia metallurgical. Silicon carbide e masani ona aofia ai faʻaoga autu e fa, e pei o: sima aoga, mea e faʻafefeteina maualuga, mea e faʻafefeteina ma faʻafefeteina mea mata. I lenei laʻasaga, e mafai ona tuʻuina atu le silicon carbide roughage i le tele o auala, e le o se oloa faʻatekonolosi, ma o le faʻaaogaina o le nano-silicon carbide paʻu ma le maualuga tele o mea faʻasaienisi ma tekinolosi e le mafai ona maua ai ni fua faʻatatau i se taimi pupuu.
(3) tioata tasi mama-maualuga, talafeagai mo le gaosiga o mea semiconductor, le gaosiga o filo vailaʻau carbide silicon.
Avanoa o le talosaga: Mo 3-12 futu photovoltaic sela, photovoltaic sela, potassium arsenide, quartz resonators ma isi laina tipi. Solar photovoltaic alamanuia, semiconductor alamanuia, piezoelectric tioata alamanuia filifili fa'ainisinia poloketi fa'ameamea mata'ina.
Reactive sintering silicon carbide – mafua'aga fa'avae
O le maualuga maualuga o le mamafa ma le maualuga o le vevela o loʻo gaosia i totonu o le eleele o loʻo sausauina mai le eleele ma le lava. E pei o Thailand, Ausetalia, Saina Shandong, Amerika ma isi atunuu. ua gaosia iasepi uamea e paʻi metamorphism. E pei o Myanmar, Kashmir, Saina Anhui ma isi itulagi. O rubi i le lalolagi e masani lava ona maua mai i tagata e tu'u. E ala i le eseese o uluai ecological emeralds, gems lanumoana e erosion aggregation reaction sintering silicon carbide ma oka silicon natura mama, carbon, slag laupapa, masima alamanuia e pei ona faavae gaosia mea mata, i totonu o le afi faavevela afi afi atagia tupulaga. O le faʻaopoopoga o le fafie fafie o le faia lea o se fasi mea faʻafefiloi i le maualuga o le vevela e maua ai se fausaga porous, lea e faʻaogaina e atagia ai le tino tele o le ausa ma le volatility e aveese ai, e puipuia ai faʻalavelave faʻafuaseʻi, ona o le augatupulaga. o le 1 tone o le silicon carbide, e mafai ona maua pe tusa ma le 1.4t o le carbon monoxide (CO). O le matafaioi a le masima fale gaosi oloa (NaCl) e faʻamalosia e aveese le alumini oxide, faʻafefiloi ma isi mea o totoe i totonu o mea.
