1. Gịnị bụ silicon carbide crucible?
Silicon carbide crucible bụ akpa dị elu nke na-eji silicon carbide (SiC) dị ka isi akụrụngwa. A na-ejikarị ya eme ihe maka ịgbaze na nhazi ọla dị iche iche na alloys. Silicon carbide bụ ihe sịntetịt nke nwere oke isi ike na nguzogide okpomọkụ. A na-eji ya eme ihe na mpaghara teknụzụ dị elu dị ka ceramics, metallurgy, na semiconductor.
N'ihi na silicon carbide crucibles nwere ọmarịcha anụ ahụ na kemịkalụ dị ka ihe nrụpụta ọkụ dị elu, ọnụọgụ mgbasawanye ọkụ dị ala, na nguzogide corrosion, ha na-egosipụta nkwụsi ike na ịdịte aka na-enweghị atụ n'okpuru oke okpomọkụ na oke ọnọdụ.
2. Nka na ụzụ uru nke silicon carbide crucible
1. Magburu onwe elu okpomọkụ iguzogide
Silicon carbide crucibles nwere oke okpomọkụ na-eguzogide ma nwee ike iguzogide okpomọkụ karịrị 1600°C. Nke a na-eme ka ha dị mma maka ịgbaze ọla ndị dị elu dị ka ọla kọpa, aluminom na nickel. N'iji ya tụnyere crucibles nke ihe ndị ọzọ, ike nke silicon carbide crucibles adịghị ebelata nke ukwuu n'okpuru ọnọdụ okpomọkụ dị elu, na-eme ka ọdịdị ya kwụsie ike n'oge usoro ịgbaze.
Nke a magburu onwe oke okpomọkụ na-eguzogide na-enyere ụlọ ọrụ aka izere crucibles site na nrụrụ ma ọ bụ mgbawa n'ihi oke okpomọkụ, si otú ahụ na-eme ka mmepụta ihe na-aga n'ihu na ịrụ ọrụ nke ọma.
2. Mma mma thermal conductivity
Ihe ọzọ a ma ama nke silicon carbide ihe bụ ihe nrụpụta ọkụ dị elu, nke na-enye ohere maka nnyefe ngwa ngwa na ọbụna okpomọkụ. Nke a pụtara na n'oge usoro mgbaze, ígwè a wụrụ awụ nwere ike iru ngwa ngwa okpomọkụ achọrọ, na-ebelata oge ịgbaze na imeziwanye mmepụta mmepụta ihe.
Usoro ikpo ọkụ a na-arụ ọrụ nke ọma na-ebelatakwa ikpo ọkụ nke ọla a wụrụ awụ, na-enyere aka nweta njikwa okpomọkụ nke ọma n'oge usoro nkedo na ịhụ na ọ dị mma nkedo.
3. Ọnụ ọgụgụ mgbasawanye ọkụ dị ala
Ọnụ ọgụgụ nke mgbasawanye thermal na-ezo aka n'ókè nke ihe na-agbasa na olu mgbe ọ na-ekpo ọkụ. Silicon carbide nwere ọnụọgụ dị oke ala nke mgbasawanye thermal, nke pụtara na ọ na-agbanwe ntakịrị nha mgbe ọ na-ekpo ọkụ. Ya mere, ọbụlagodi na gburugburu ebe nwere nnukwu mgbanwe okpomọkụ, silicon carbide crucible nwere ike idowe ọdịdị mbụ ya ma zere mgbawa ma ọ bụ mmebi n'ihi mgbasawanye ma ọ bụ nkwụsị.
Mgbasawanye okpomọkụ dị ala dabara adaba maka usoro nkedo nke metụtara usoro ikpo ọkụ na oyi na-ekpo ọkụ, na-agbatịkwu ndụ ọrụ nke crucible.
4. Magburu onwe corrosion eguzogide
N'oge a na-agbaze agbaze, ígwè a wụrụ awụ na-emeghachi omume na crucible, jiri nwayọọ nwayọọ na-emebi elu ya. Otú ọ dị, silicon carbide ihe nwere magburu onwe kemịkalụ nguzogide corrosion na nwere ike n'ụzọ dị irè iguzogide mbuze nke metal mmiri mmiri, karịsịa mgbe a na-emeso nke ukwuu reactive ọla dị ka ọla kọpa na aluminom.
Ezigbo nguzogide corrosion ọ bụghị naanị na-agbatị ndụ ọrụ nke crucible, kamakwa ọ na-ebelata mmetọ adịghị ọcha nke na-eme ka ọ bụrụ ihe na-adịghị mma nke na-eme ka ọ dị ọcha n'elu ala, na-eme ka ịdị ọcha nke mmiri mmiri dị ọcha na-eme ka mma nke ngwaahịa ikpeazụ dịkwuo mma.
5. Ike igwe dị elu
Silicon carbide crucibles na-ejigide ike ọrụ dị elu ọbụlagodi na oke okpomọkụ, na-eme ka ọ ghara imebi ma ọ bụ mebie. Njirimara a dị elu na-eme ka crucible nwee ike iguzogide mmetụta nke ígwè a wụrụ awụ na nrụgide n'èzí, na-ejigide nkwụsi ike nhazi n'oge okpomọkụ dị elu.
6. Ezigbo ujo nkwụsi ike
Nkwụsi ike nke okpomọkụ na-ezo aka n'ikike nke ihe nwere ike iguzogide mgbawa mgbe okpomọkụ na-agbanwe ngwa ngwa. Silicon carbide crucibles na-egosipụta nkwụsi ike dị mma na-ekpo ọkụ ma nwee ike iguzogide mgbanwe okpomọkụ ngwa ngwa na-enweghị mgbawa. Nke a dị mkpa karịsịa maka usoro nkedo nke na-achọ ikpo ọkụ na oyi mgbe niile.
atọ. Ngwa nke silicon carbide crucible
N'ihi nkwụsi ike ya dị elu dị elu, nrụpụta okpomọkụ, na nguzogide corrosion, silicon carbide crucibles na-ejikarị eme ihe n'ụdị dị iche iche nke mgbaze na nkedo ígwè, karịsịa na mgbaze nke ọla ndị na-adịghị ferrous na alloys. Ndị a bụ ọtụtụ ndapụta ngwa ngwa:
Nkedo ọla kọpa: Mgbe a na-agbaze ọla kọpa.silicon carbide crucibles nwere ike na-agbaze okpomọkụ edo, ibelata guzobe nke adịghị ọcha, na melite àgwà ọla kọpa akụkụ.
Aluminom na aluminom alloy na-agbaze: Aluminom na-emeghachi ngwa ngwa na crucible n'oge usoro mgbaze, mana nguzogide corrosion nke silicon carbide na-echebe nke ọma na crucible na corrosion aluminom ma gbatịa ndụ ọrụ ya.
Mgbaze ọkụ ndị ọzọ dị elu: Silicon carbide crucible dịkwa mma maka ịgbaze ọla ndị dị elu dị ka zinc na nickel, ma nwee ike ime mgbanwe.
Anọ. Iji na mmezi nke silicon carbide crucible
Iji gbatịa ndụ ọrụ silicon carbide crucibles, iji ziri ezi na mmezi dị oke mkpa. Nke a bụ aro ụfọdụ:
Kpoo ọkụ n'ọkụ: Tupu iji ya mee ihe ma ọ bụ megharịa ya, a na-atụ aro ka iji nwayọọ kpoo ọkụ ahụ ka ọ dị ọkụ iji gbochie ikpo ọkụ na mgbawa na mberede.
Zere ikpo ọkụ ngwa ngwa na jụrụ oyi: Ọ bụ ezie na silicon carbide crucibles nwere ezigbo ujo nkwụsi ike, oke okpomọkụ mgbanwe ngwa ngwa ka nwere ike imebi crucible.
Nleba anya mgbe niile: Mgbe ị na-eji ya, na-elele elu crucible mgbe niile maka akara mgbawa ma ọ bụ corrosion, ma dozie nsogbu ndị nwere ike ime n'oge.
