Ibyiciro byinshi bya Magnesium-Aluminium Spinel Icyiciro: Sma-66, Sma-78 na Sma-90.Ibicapo bya Spinel Ibicuruzwa bikurikirana

• Junsheng-yuzuye-magnesium-aluminium spinel ifite ibintu bikurikira:
• Kurwanya cyane;
• Ubushyuhe bwo hejuru buringaniye;
• Kurwanya bihebuje kurwanya alkaline slag ruswa no kwinjira;
• Guhagarika ubushyuhe bwiza.

Amabuye y'agaciro ya spinel agira uruhare runini kumiterere yubushyuhe bwo hejuru bwibikoresho byangiritse.Kurugero, kubera coefficente ntoya yo kwagura ubushyuhe bwa spinel (α = 8.9x10 - * / ℃ kuri 100 ~ 900 ℃), spinel ikoreshwa nkibikoresho bihuza (Cyangwa bita cementing phase, matrix), amatafari ya magnesia-alumina hamwe na periclase nkicyiciro nyamukuru cya kristu, iyo ubushyuhe buhindutse cyane, imihangayiko yimbere yabyaye ni nto, kandi amatafari ntabwo yoroshye kumeneka, bityo ituze ryumuriro wamatafari rirashobora kunozwa (amatafari ya magnesia-alumina Ubushyuhe bwumuriro ni 50 ~ 150 ibihe).

Byongeye kandi, kubera ko spinel ifite ibintu byiza nko gukomera cyane, imiti ihamye ya chimique, hamwe no gushonga cyane, kandi ikarwanya cyane kwangirika kwishongora ryubushyuhe butandukanye, kuba minerval spinel mubicuruzwa byazamuye imikorere yubushyuhe bwo hejuru bwa ibicuruzwa.

Impamvu nyamukuru ituma ubushyuhe bwo hejuru bworoshya ubushyuhe bwamatafari ya magnesia-alumina (aho gutangirira ntabwo buri munsi ya 1550-1580 ℃) burenze ubw'amatafari ya magnesia (aho gutangirira munsi ya 1550 ℃) nuko ibice bya matrix bitandukanye. .

Mu ncamake, spinel nibikoresho byiza cyane mubijyanye no gushonga, kwaguka kwubushyuhe, gukomera, nibindi, bifite imiti ihagaze neza, kurwanya isuri ya alkaline, no kurwanya isuri yashonze .Gereranya nibintu bya spinel nizindi oxyde. .
