Iyo indasitiri yekugadzira nzira yekuita-sintered silicon carbide inofanirwa kunge iri yemhando yepamusoro

Iyo indasitiri yekugadzira nzira ye reaction-sintered silicon carbide ndeyekubvisa yakakwira mhando yequartz jecha uye calcined petroleum coke muchoto chekupisa chemagetsi. Iyo yakacheneswa silicon carbide zvidhinha inogadzirwa kuita zvigadzirwa zvine akasiyana particle saizi kugoverwa nekupwanya, yakasimba asidhi uye alkali washing, magineti yekuparadzanisa michina uye kuongorora kana kupatsanurwa kwemvura.

Silicon carbide ine maviri akajairwa emhando mhando dzeblack silicon carbide uye yegirini silicon carbide, ese ari e-α-SiC. ① Black silicon carbide ine inenge 95% SiC, uye ductility yayo yakakwirira kupfuura yegirini silicon carbide, mazhinji ayo anoshandiswa kugadzira nekugadzira zvinhu zvakasvibirira zvine simba rakaderera, senge laminate girazi, porcelain, dombo, refractory, simbi yenguruve uye simbi dzinokosha. ② Green silicon carbide ine SiC inosvika 97% pamusoro, kuzvirodza kwakanaka, mazhinji acho anoshandiswa kugadzira uye kugadzirisa maturusi ecarbide, titanium simbi uye optical lenses, uye anoshandiswawo kukudza humburumbira liner uye kupukuta kukurumidza-kumhanya. midziyo yesimbi. Pamusoro pezvo, kune cubic metres yesilicon carbide, iri girini yakasvibira kristaro yakagadzirwa nemaitiro matsva, uye inoshandiswa kugadzira mold inokodzera kutakura super-kupedzisa, iyo inogona kuita roughness kubva kuRa32 ~ 0.16μm kugadzirisa. kusvika Ra0.04 ~ 0.02μm.

Kunyanya kushandiswa kwekuita sintering silicon carbide

(1) Sechinhu chinodzivirira kupfeka, chinogona kushandiswa seforoma, senge vhiri rejecha, whetstone, vhiri rekukuya, jecha tile, nezvimwe.

(2) Se deoxidizing mumiriri uye ngura inodzivirira zvinhu zveindasitiri yesimbi. Silicon carbide inonyanya kusanganisira ina mashandisirwo makuru, anoti: anoshanda ceramics, high-end refractory zvinhu, kupfeka-resistant zvinhu uye kunyungudutsa mbishi. Panguva ino, silicon carbide roughage inogona kupihwa nenzira dzakawanda, isiri chigadzirwa chepamusoro-soro, uye kushandiswa kwenano-silicon carbide poda ine yakakwira zvakanyanya zvesainzi uye tekinoroji hazvigone kuburitsa chiyero munguva pfupi.

(3) high-purity single crystal, yakakodzera kugadzirwa kwezvinhu zvesemiconductor, kugadzirwa kwesilicon carbide chemical fibers.

Kuwanda kwekushandisa: Kwema 3-12 tsoka photovoltaic masero, photovoltaic masero, potassium arsenide, quartz resonators uye mamwe mutsara wekucheka. Solar photovoltaic indasitiri, semiconductor indasitiri, piezoelectric crystal industry chain engineering project raw material processing.

Reactive sintering silicon carbide - zvikonzero zvekugadzira

Iyo yakanyanya-yakanyanya kudzvanywa uye yakakwirira tembiricha mwero inogadzirwa mupakati penyika inopfapfaidzwa kubva pasi nebota. Zvakadai seThailand, Australia, China Shandong, United States nedzimwe nyika. Simbi jade inogadzirwa nekubata metamorphism. Zvakadai seMyanmar, Kashmir, Anhui yeChina uye mamwe matunhu. Rubies munyika inonyanya kutorwa kubva kune placers. Iri kuburikidza neakasiyana epakutanga ecological emeralds, matombo ebhuruu ne erosion aggregation reaction sintering silicon carbide ine yakachena yakasikwa silicon ore, kabhoni, huni slag, munyu weindasitiri seyakagadzirwa zvinhu zvakabikwa, mumagetsi ekupisa muchoto kupisa kunoratidzwa chizvarwa. Kuwedzerwa kwehuni slag ndiko kuita chidimbu chiduku chechinhu chakavhenganiswa pakupisa kwepamusoro kuti ibudise chimiro cheporous, iyo inobatsira kuratidza yakakura-yakakura mhute muviri uye kusagadzikana kubva kwairi kubvisa, kudzivirira njodzi dzekuputika, nekuda kwechizvarwa. ye 1 toni yesilicon carbide, inogona kugadzira inenge 1.4t yecarbon monoxide (CO). Basa remuindasitiri munyu (NaCl) rinobatsira kubvisa aluminium oxide, makomisheni uye zvimwe zvakasara mune izvo zvinhu.
