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 ma le 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'aiga 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 le 3-12 futu photovoltaic sela, sela photovoltaic, potassium arsenide, quartz resonators ma isi laina tipi. Solar photovoltaic alamanuia, semiconductor alamanuia, piezoelectric tioata alamanuia filifili inisinia galuega faatino mata'ina mea.
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 faʻapipiʻi. 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.
