1. O siri ike nke ukwuu: "onye na-ebu" n'ọhịa nke iguzogide iyi
Uru kacha mara amara nke siliki carbide ceramics bụ ike siri ike ya na iyi nguzogide. Isi ike Mohs ya bụ nke abụọ na diamond kacha sie ike na okike, siri ike karịa igwe nkịtị, igwe anaghị agba nchara, na ọbụna seramiki alumina.
Àgwà 'hardcore' a na-eme ka ọ na-egbuke egbuke n'ọnọdụ ebe ọ kwesịrị iguzogide iyi na akwa. Dị ka ihe atụ, na Ngwuputa na metallurgical ụlọ ọrụ, ngwá maka ibufe slurry na slag slurry (dị ka impellers nke slurry nfuli na pipeline liners) na-na-na-na-na-na-na-na-na-na-na-na-na-esi ike ịnweta irighiri ruo ogologo oge, na nkịtị ọla ga-ngwa ngwa na-emebi slurry na ntapu mmiri. Ngwa ndị ejiri seramiiki silicon carbide nwere ike iguzogide “abrasion” a n'ụzọ dị mfe ma nwee ndụ ọrụ ọtụtụ oge ma ọ bụ karịa okpukpu iri nke ihe igwe, na-ebelata ugboro ole na ọnụ ahịa nnọchi akụrụngwa.
Ọ bụghị naanị na ntọala ụlọ ọrụ, anyị nwekwara ike ịhụ ọnụnọ ya na ndụ kwa ụbọchị - dị ka ụdị esemokwu silicon carbide na akara igwe.

2, Elu "Nguzogide": mkpuchi maka oke okpomọkụ na corrosion
Na mgbakwunye na ike siri ike, seramiiki silicon carbide nwekwara oke nguzogide okpomọkụ dị elu na nguzogide corrosion, nke na-enye ha ohere "rapara n'oche ha" n'ọtụtụ "gburugburu ebe siri ike".
N'ihe banyere nguzogide okpomọkụ dị elu, ọbụlagodi mgbe arụ ọrụ ogologo oge gasịrị na 1350 ℃, a gaghị enwe nro ma ọ bụ nrụrụ. Njirimara a na-eme ka ọ bụrụ "onye na-agba ọsọ" na ụgbọ elu na ụlọ ọrụ ndị agha, dị ka ihe eji eme ihe maka igwe rọketi, mkpuchi maka ọkụ ọkụ dị elu, wdg. Ọ nwere ike ịkpọtụrụ ọkụ ọkụ ma ọ bụ ọla a wụrụ awụ ozugbo iji nọgide na-akwụsi ike. Na elu okpomọkụ mmepụta usoro dị ka ulo oru kilns na metallurgical na-aga n'ihu nkedo, silicon carbide seramiiki components nwekwara ike dochie ọla na-adị mfe mebiri site elu okpomọkụ, ịgbatị ndụ akụrụngwa ndụ.
N'ihe gbasara nguzogide corrosion, ceramik silicon carbide nwere nkwụsi ike kemịkalụ siri ike. Ma ọ̀ bụ acid, alkali, ma ọ bụ gas na mmiri mmiri dị iche iche na-emebi emebi, ọ na-esi ike ‘ibibie’ ya. Ya mere, na ụlọ ọrụ kemịkalụ, a na-ejikarị eme ihe mkpuchi nke arịa mmeghachi omume, pipeline na valves maka ibufe mgbasa ozi na-emebi emebi; N'ihe gbasara nchekwa gburugburu ebe obibi, a pụkwara ịhụ ọnụnọ ya na ngwá ọrụ maka ịgwọ oke mmiri mmiri na-ekpo ọkụ nke acid-base, hụ na ngwá ọrụ adịghị emebi emebi ma na-arụ ọrụ nke ọma.
3, "Ikike" dị iche iche: "Nna-ukwu na-arụ ọrụ" nke nwere ike ịbụ ma isi ike na mgbanwe.
Ọ bụrụ na ị na-eche na silicon carbide ceramik bụ naanị "ike" na "na-adịgide adịgide", mgbe ahụ ị na-eleda ha nke ukwuu. Dị ka usoro nhazi dị iche iche si dị, ọ pụkwara inwe ọtụtụ ọrụ dị ka conductivity, mkpuchi, na thermal conductivity, na-eme ka ọ bụrụ ihe na-arụ ọrụ nke nwere ọtụtụ ojiji.
-Conductivity na semiconductor Njirimara: Site na doping na ihe ndị ọzọ, silicon carbide ceramics nwere ike ịgbanwe si insulators na-eduzi, na ọbụna ghọọ semiconductor ihe. Nke a na-enye ya ohere igosipụta nkà ya n'ọhịa nke eletriki eletrik, dị ka ịme modul ike maka ụgbọ ala ike ọhụrụ na isi ihe maka ndị na-atụgharị traction na ụgbọ oloko dị elu. E jiri ya tụnyere ihe siliki ọdịnala, silicon carbide semiconductors nwere arụmọrụ conductivity dị elu yana obere ike oriri, nke nwere ike ime ka ụgbọ ala ume ọhụrụ na-ebu ngwa ngwa ma nwee ogologo ogologo, na-emekwa ka akụrụngwa ike dị ntakịrị ma rụọ ọrụ nke ọma.
-Ezigbo conductivity thermal: The thermal conductivity nke silicon carbide ceramics karịrị nnọọ nke ceramik nkịtị, na ọbụna na-eru nso nke ụfọdụ ọla. Njirimara a na-eme ka ọ bụrụ ihe na-ekpo ọkụ na-ekpo ọkụ dị mma, dịka ọmụmaatụ, na ọkụ ọkụ ọkụ ọkụ nke ọkụ ọkụ LED na ibe eletriki, ọ nwere ike ime ngwa ngwa na-ekpo ọkụ, gbochie ngwá ọrụ ka ọ ghara imebi n'ihi oke ọkụ, ma melite ndụ ọrụ na nkwụsi ike.
4, N'ikpeazụ: Silicon carbide ceramics, 'ike ịnya ụgbọ ala na-adịghị ahụ anya' nke nkwalite ụlọ ọrụ.
Site na "ike na eyi-eguzogide" na "elu okpomọkụ corrosion eguzogide", na mgbe ahụ na "multifunctionality", silicon carbide ceramics agbajila ndị mmadụ nghọta nke omenala ceramics na a usoro nke magburu onwe Njirimara, na-aghọ a isi ihe onwunwe na-akwado mmepe nke elu-ọgwụgwụ n'ichepụta, ọhụrụ ume, ike nchekwa na gburugburu ebe obibi nchebe. Ọ bụghị ihe a na-ahụkarị dị ka ígwè ma ọ bụ dị arọ dị ka plastik, ma na ọnọdụ mmepụta ihe nke na-achọ "ịmeri ihe isi ike", ọ na-adabere mgbe niile na njirimara "enweghị ike" ya ka ọ bụrụ isi ihe na-edozi nsogbu.
Site na ọganihu nke teknụzụ na-aga n'ihu, ọnụ ahịa mmepụta nke silicon carbide ceramics na-eji nwayọọ nwayọọ na-ebelata, na ihe ngosi ngwa na-agbasawanye mgbe niile.
