Ihe mkpuchi seramiiki silicon carbide

Ihe mkpuchi na-eguzogide iyi silicon carbide

Atụmatụ Nhazi nke ihe mkpuchi Silicon Carbide (SiC) nke na-eguzogide iyi:

(1) Nhazi Ụzọ Mmiri Na-agbagharị

Usoro dị nro ma dị mfe site na mbata ruo na mpụga na-ebelata iguzogide mmiri, na-eme ka eriri SiC dị mfe ịgbanwe maka ngwa ụlọ ọrụ dị iche iche.

(2) Ntọhapụ Atom dị elu

Usoro A na-eme ka mmiri dị n'ime obere ntụpọ site na mgbakasị tangential na-ebelata elu helical nke liner SiC na-ebelata, na-ahụ na ekesara otu usoro ịgbasa.

(3) Ọdịdị dị obere, nke na-enweghị mkpọchi

Ọwa mmiri na-aga n'ihu nke na-enweghị isi na-ewepụ ihe mgbochi dị n'ime, na-eme ka mmepụta mmiri dị elu n'ime oke paịpụ dị mkpụmkpụ ma na-egbochi mkpọchi.

(4) Ụdị ịgba abụọ maka arụmọrụ ka mma

Na-akwado ma usoro ịgba mmiri siri ike ma nke nwere oghere, na-enye akụkụ mkpuchi sara mbara yana arụmọrụ mgbochi mkpọchi maka ọrụ dị elu.

Isi uru ma e jiri ya tụnyere ihe ndị ọzọ:

(1) Mgbochi iyi na-enweghị atụ

Ike siri ike: ihe mkpuchi SiC na-enweta ike Mohs nke 9.5 (vs. 8.0 maka seramiiki alumina, 6.0 maka ígwè chromium dị elu), na-eme ka ha nwee ike iguzogide oke mmebi na slurries nke igwu ala, ntụ coal, na ntụ ígwè.

Ogologo oge: Ndụ ọrụ karịrị ihe ọdịnala 5-10 × (dịka ọmụmaatụ roba ma ọ bụ polyurethane liner) na ngwa ndị nwere mmetụta dị elu dịka igwe bọọlụ ma ọ bụ ọkpọkọ slurry.

(2) Njehie na enweghị ike ime ihe ọ bụla gbasara kemịkalụ

Nguzogide Asịd/Alkali: Ọ na-eguzogide acid sulfuric a chịkọtara (98%), sodium hydroxide (50%), na nnu agbazere agbaze (dịka ọmụmaatụ NaCl-KCl na 800°C), ebe ọla na-emebi ngwa ngwa ma polymers na-emebi.

Ntanye efu: Elu na-anaghị emeghachi omume na-eme ka ịdị ọcha dị na mmepụta batrị semiconductor ma ọ bụ lithium, n'adịghị ka ihe mkpuchi ígwè nwere ike ịdaba na ion.

(3) Oke Okpomọkụ Nkwụsi Ike

Nkwụsi Ike nke Okpomọkụ: Na-arụ ọrụ mgbe niile na 1,600°C (ma e jiri ya tụnyere oke 1,200°C nke alumina) yana obere mgbasawanye okpomọkụ (CTE: 4.0×10⁻⁶/℃), na-egbochi mgbawa n'ime ọkụ ma ọ bụ ọkụ na-agbaze.

Nguzogide Mkpọchi Okpomọkụ: Na-ejigide iguzosi ike n'ezi ihe n'okpuru mgbanwe okpomọkụ ngwa ngwa (dịka ọmụmaatụ, imenyụ site na 1,000°C ruo okpomọkụ ụlọ), n'adịghị ka seramiiki na-agbawa agbawa.

(4) Ike na Nhazi Dị Mfe

Nsogbu Dị Ala: Elu SiC e ji mma mee (Ra <0.1 μm) na-ebelata iguzogide mmiri site na 30-50% ma e jiri ya tụnyere ihe mkpuchi ígwè siri ike, na-ebelata ọnụ ahịa ike mgbapụta.

Nchekwa Ibu: Njupụta nke 3.1 g/cm³ (ma e jiri ya tụnyere 7.8 g/cm³ nke ígwè) na-eme ka ntinye dị mfe ma na-akwado ngwa dị fechaa na ngalaba nhazi ikuku ma ọ bụ mkpanaka.

Shandong Zhongpeng Special Ceramics Co., Ltd bụ otu n'ime ihe ngwọta ọhụrụ seramiiki silicon carbide kachasị ukwuu na China. Seramiiki teknụzụ SiC: Ike Moh bụ 9 (ike Moh ọhụrụ bụ 13), yana ezigbo iguzogide mbuze na nchara, ezigbo nbibi - iguzogide na mgbochi oxidation. Ndụ ọrụ nke ngwaahịa SiC dị okpukpu 4 ruo 5 karịa ihe alumina 92%. MOR nke RBSiC bụ ugboro 5 ruo 7 nke SNBSC, enwere ike iji ya maka ụdị ndị ka mgbagwoju anya. Usoro nhota dị ngwa, nnyefe dị ka ekwere nkwa na ịdị mma ya adịghị elu. Anyị na-anọgide na-agba mbọ mgbe niile n'ịma aka ebumnuche anyị ma na-enye obi anyị nye ọha mmadụ.
