Menene bambanci tsakanin farin corundum da alumina

Farin corundum da alumina ba abu ɗaya ba ne. Dangane da dalilin, bari edita daga Henan Sicheng ya gaya muku dalla-dalla: Menene bambanci tsakanin farin corundum da alumina?

1. Farin corundum wani abu ne na wucin gadi wanda aka yi da alumina a matsayin albarkatun kasa kuma ya narke kuma yana sanyaya a babban zafin jiki. Alumina wani babban taurin fili ne.

2. Babban bangaren farin corundum shine alumina. Musamman, shi ne nau’in crystal na alumina, wato α-Al2O3. Baya ga alumina, akwai ƙananan ƙazanta irin su baƙin ƙarfe oxide da silicon oxide. Alumina ne barga oxide na aluminum. Babban abubuwan shine oxygen da aluminum, kuma tsarin sinadaran shine alumina. Akwai lu’ulu’u iri-iri masu yawa da marasa daidaituwa, kamar α-Al2O3, β-Al2O3 da γ-Al2O3.

3. Jiki Properties The narkewa batu na farin corundum ne 2250 ℃, da kuma bayyanar crystal form ne trigonal crystal. Matsayin narkewar alumina yana ƙasa da 2010 ° C-2050 ° C. Siffar sa fari foda ne, kuma lokacin crystal ɗin sa γ lokaci ne.

4. Farin corundum gabaɗaya ana amfani da shi wajen kera kayan abrasives, amma kuma ana iya amfani da su a masana’antu kamar su masu kara kuzari, masu hana ruwa, simintin gyare-gyare, da fashewar yashi. Ana amfani da Alumina galibi a cikin masana’antu kamar sarrafa zafi, goge goge, electroplating, da masu kara kuzari.
