Farqiga u dhexeeya ceramics alumina iyo ceramics hufan

Fikrado kala duwan

Alumina dhoobadawaa nooc ka mid ah walxaha dhoobada leh alumina (AI203) oo ah jirka ugu weyn.

ceramics hufan waxaa lagu helaa iyadoo la isticmaalayo sifooyin sare ultra-fine dhoobada alaabta ceeriin iyo baabi'inta daloolada by hab tignoolajiyada.

Halabuurka iyo kala soocidda ayaa kala duwan

Alumina ceramicswaxaa loo kala qaybiyaa nooca nadiifka sare ah iyo nooca caadiga ah ee labaad.

dhoobada alumina ee nadiifka ah ee nadiifka ah waa walxo dhoobo ah oo leh AI203 ka sarreeya 99.9%.℃iyo hirarka gudbinta ee 1 ~ 6um, waxaa guud ahaan laga sameeyaa galaas dhalaalid ah si ay u qaataan jiil of platinum crucible; U isticmaal gudbinteeda iftiinka iyo iska caabbinta birta alkali sida tuubada laambada sodium; Waxa loo isticmaali karaa sidii guddi wareeg ah oo isku dhafan iyo walxaha dahaarka inta jeer ee sare ee warshadaha elektiroonigga ah.

Caadiyanaluminium ceramicsWaxaa loo qaybiyaa 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain iyo noocyo kale marka loo eego nuxurka A1203, marmarka qaarkoodna A1203 waxa lagu kala saaraa taxane dhoobada caadiga ah. Qalabka dhoobada ah ee 99 alumina waxaa loo isticmaalaa in lagu sameeyo heerkul sarreeya, tuubo foornada refractory iyo qalab gaar ah oo u adkaysta, sida dhoobada dhoobada, shaabada dhoobada iyo biyaha; 95 alumina porcelain waxaa inta badan loo isticmaalaa iska caabbinta daxalka oo xidho qaybo iska caabin ah; 85-ka porcelain waxaa inta badan lagu daraa talc si loo hagaajiyo sifooyinka korontada iyo xoogga farsamada, waxaana lagu xiri karaa molybdenum, niobium, tantalum iyo biraha kale, qaarna waxaa loo isticmaalaa qalab koronto ah.

dhoobada hufan waxaa loo qaybin karaa aluminium oxide ceramics hufan, yttrium oxide ceramics hufan, magnesium oxide ceramics hufan, yttrium aluminium garnet ceramics hufan, aluminium magnesium acid ceramics hufan, dhoobada hufan ferroelectric, aluminium nitride dhoobada hufan, aluminium nitride aluminium spinics transparent ceramics hufan iyo wixii la mid ah.

 

Waxqabad kala duwan

Alumina dhoobadaguryaha

1. engegnaanta sare waxaa go'aamiyay Machadka Shanghai ee Silicate ee Akadeemiyada Sayniska Shiinaha, engegnaantiisa Rockwell waa HRA80-90, engegnaanta waa labaad ee kaliya ee dheeman, aad uga badan caabbinta xirashada ee birta xidhashada u adkaysata iyo birta aan lahayn.

2. Iska caabbinta xidhashada heer sare ah oo lagu qiyaaso machadka budada budada ee Jaamacadda Central South University, iska caabinteedu waxay u dhigantaa 266 jeer oo birta manganese ah iyo 171.5 jeer birta chromium sare leh. Marka loo eego sahanka macaamiisheena in ka badan toban sano, isla xaaladaha shaqada, nolosha adeegga qalabka waa la kordhin karaa ugu yaraan toban jeer.

3. Miisaanka fudud Cufkiisu waa 3.5g/cm3, taas oo ah kala badh birta, taas oo aad u yareyn karta culeyska qalabka.

 

Tilmaamaha dhoobada hufan:

Ceramics Transparent sida laan ka mid ah ceramics horumarsan, marka lagu daro in la dhaxlo dhoobada caabbinta heerkulka sare, caabbinta daxalka, xoog sare, adkaanta sare, xasiloonida kiimikada, coefficient hooseeyo ballaarinta marka lagu daro, gudbinta iftiinka gaar ah ka dhigaysa in ay kordhiso codsiyada badan.

 

Codsi kala duwan

Alumina ceramicswaxaa si weyn loogu isticmaalaa mishiinada, fiber indhaha, qalabka goynta, caafimaadka, cuntada, kiimikaad, hawada iyo warshadaha kale.

dhoobada hufan waxaa inta badan loo isticmaalaa qalabyada nalka, alaabta laysarka, alaabta daaqadaha infrared, ceramics flicker, ceramics electro-optical, alaabta aan xabadu karin.
