Amatafari yo gutwika ya alumina silica ni ubwoko bw'ibikoresho birwanya silika ya alumina, amatafari yo gutwika ya alumina silica afite imiterere yo kudakomera cyane, kurwanya isuri neza kandi akomeye cyane. Amatafari yo gutwika ya alumina silicate arimo ubwoko bwinshi bw'amatafari yo gutwika nka amatafari ya silica, amatafari y'ibumba, amatafari menshi ya alumina, amatafari ya mullite na corundum. Amatafari yo gutwika ya alumina silica ashobora gukoreshwa mu bikoresho byose bishyushya.
Ubwoko bw'amatafari y'umuriro ya Alumina Silika
Dukurikije uko ibintu byiyongera kuva kuri SiO2 kugera kuri Al2O3, amatafari ya silikoni ya aluminiyumu ashyirwa mu byiciro bikurikira
Amatafari ya silica: ingano ya SiO2 irenga 93%,
Amatafari y'ibumba: ingano ya Al2O3 ni 30%-48%,
Amatafari menshi ya alumina: ingano ya Al2O3 irenze 48%,
Amatafari menshi: ingano ya Al2O3 iruta cyangwa ingana na 72%, naho ingano ya SiO2 iruta cyangwa ingana na 28%,
Itafari rya Corundum: ingano ya Al2O3 irenga 90%.
Gukoresha amatafari yo gutwika ya Alumina Silika
Amatafari ya silica akoreshwa cyane cyane mu kubaka ifuru ya coke, ifuru y'ibirahure, ifuru ya ceramic, ifuru ya carbon calcinations kandi ntabwo akwiriye gukoreshwa mu bikoresho bishyushya bifite ihindagurika ry'ubushyuhe riri munsi ya 600 ℃.
Amatafari y'ibumba akoreshwa buri gihe mu itanura rishyuha, icyuma gishyushya gishyuha, itanura rishyushya, icyuma gishyushya gitanga umuriro, itanura ry'indimu, itanura rizunguruka, itanura rya ceramic n'itanura rikoresha calcium.
Amatafari menshi ya alumina akoreshwa cyane cyane mu gukora ibyuma, inganda z'ibyuma bidakoresha feri n'izindi nganda.
Amatafari ya Mullite akoreshwa mu bwoko bwose bw'ibikoresho byo mu nganda bishyushye kandi bikozwe mu mavuta mu nganda zikora ibyuma, ibikomoka kuri peteroli, ibikoresho by'ubwubatsi, inganda zikora ibumba, n'inganda zikora imashini.
Amatafari ya Corundum ashobora gukoreshwa mu itanura riturika, mu ziko rishyushye riturika, mu itanura ry'ibirahure n'ibindi.
Ibiranga amatafari yo gutwika ya Alumina Silika
- Kudakomera cyane,
- Ubudahangarwa bwiza bw'ubushyuhe,
- Ubudahangarwa bukomeye bw'isuri,
- Ubushyuhe bwinshi,
- Igipimo cyo kwaguka k'ubushyuhe gito,
- Ubushyuhe bwinshi butwara umuvuduko.

Uruganda rukora amatafari ya silica ya alumina
Uruganda rukora amatafari arwanya ubushyuhe bwa RS nk'umwe mu ruganda rukora amatafari arwanya ubushyuhe bw'itanura, rwihariye mu gukata no gutunganya amatafari arwanya ubushyuhe bw'amatafari hakurikijwe ibyo abakiriya bakeneye, ibyo bikaba bishobora kugufasha gukora amatafari ya silica yo mu rwego rwo hejuru ya alumina.
