Polycrystalline Al2O3 alumina ceramics ahaziri elu okpomọkụ eyi nguzogide

Nkọwa dị mkpirikpi:

Alumina ceramics (Al203) bụ ihe seramiiki ziri ezi na-eguzogide iyi nke a na-ejikarị na ụlọ ọrụ dị iche iche. Ụzọ isi ịkpụzi maka ngwaahịa seramiiki alumina bụ ịpị ọkpọkọ, ịpị isostatic, ịkpụzi injection na nkedo, wdg. Ụdị ngwaahịa dị iche iche, nha na nkenke chọrọ ụzọ ịkpụzi dị iche iche. Mgbe ikpochasị ọkụ dị elu nke ngwaahịa seramiiki alumina, naanị iji usoro egweri diamond nwere ike ịhazi. Ịdị ọcha nke seramiki alumina nkịtị bụ 90% -99.9%.

Aluminom oxide ceramics arụmọrụ

1--isi ike dị elu

Rockwell siri ike nke seramiki alumina bụ HRA80-90, nke abụọ na diamond na ike siri ike, karịa karịa igwe anaghị agba nchara na igwe anaghị agba nchara.

2--Ezigbo mgbochi iyi

Nguzogide iyi nke seramiki alumina bụ oge 266 nke ígwè manganese na oge 171.5 nke nnukwu ihe nkedo chromium. N'okpuru otu ọnọdụ ọrụ ahụ, ọ nwere ike ịgbatị ndụ ọrụ nke akụrụngwa ma ọ dịkarịa ala ugboro iri.

3--Mfe arọ

Njupụta nke alumina ceramics bụ 3.7 ~ 3.95g / cm °, nke bụ naanị ọkara nke ígwè na ígwè, ma nwee ike ibelata ibu ngwá ọrụ.

4--N'obosara Ngwa

A na-eji seramiiki alumina eme ihe na igwe, fiber optics, ngwaọrụ ịkpụ, ahụike, nri, kemịkalụ, ikuku ikuku na mpaghara ndị ọzọ.

Uru nke alumina ceramics:

1--Alumina ceramics nwere ihe mkpuchi mkpuchi mara mma. Ọnwụ nke dị elu dị ntakịrị, na mkpuchi mkpuchi dị elu dị mma.

2--Alumina ceramics nwere nguzogide okpomọkụ, obere ọnụọgụ nke mgbasawanye thermal, ike igwe dị elu na ezigbo ọkụ ọkụ.

3--Alumina ceramics nwere nguzogide kemịkalụ na nguzogide ọla a wụrụ awụ.

4--Alumina ceramics na-adịghị ọkụ, ọ dịghị mfe nchara na ike na-adịghị mfe imebi, na ndị ọzọ organic ihe na metal ihe-apụghị tụnyere ndị magburu onwe àgwà.

5-Alumina ceramics dị elu na-eyi nguzogide, isi ike na corundum otu, nwere ike iru Mohs hardness 9, nguzogide iyi ya nwere ike dakọtara na alloys siri ike.
