Ububiko bw'ubushyuhe n'ububiko bw'ubushyuhe bw'amatanura ya alumina mu nganda
Umupira wa keramike ubikwamo ubushyuhe ukozwe muri alumina y’inganda na kaolini idashobora guhindurwa nk’ibikoresho by’ingenzi. Wakozwe mu buryo bwa siyansi, ufite ishusho kandi ukanashyirwamo calcium ku bushyuhe bwinshi. Ufite imiterere myiza:
1) Ingufu nyinshi za mekanike kandi zimara igihe kirekire;
2) Gukomera neza mu binyabutabire, nta mikorere ya shimi ikoreshwa n'ibikoresho;
3) Ubudahangarwa bwiza ku bushyuhe buri hejuru, ubushyuhe bwinshi bushobora kugera kuri 1900°C.
| Ikintu | Umupira wo kubikamo ibintu bikonje | Umupira wo kubika ubushyuhe |
| Al₂O₃ (%) | 20-30 | ≥65 |
| SiO₃+Al₂O₃(%) | ≥90 | |
| Fe₂O₃(%) | ≤1 | ≤1.6 |
| Ingano (mm) | 10-20/20-40 | 16-18/20-25 |
| Ubushobozi bwo gushyuha (J/kg.k) | ≥836 | ≥1000 |
| Ubushobozi bwo gutwara ubushyuhe (w/mk) | 2.6-2.9 | 2-4 |
| Ubudahangarwa bw'ihungabana ry'ubushyuhe (℃) | 800 | 1000 |
| Ubushobozi bwo kugarura umwuka (℃) | 1550 | 1750 |
| Igihombo cyo kwangirika (%) | ≤0.1 | |
| Ubukana bwa Mohs (igikanka) | ≥6.5 | |
| Imbaraga zo gusya (N) | 800-6000 | 1800-3800 |
| Ubucucike bw'umubyimba (kg/m3) | 1300-1400 | 1500-1600 |
1) Ikwiriye cyane cyane amatanura y’ubushyuhe buri hejuru n’ubushyuhe buke, amavugurura, amahindura amazi, ibigega byo gusukura ikirere n’amatanura ya methanase mu nganda zifumbira ifumbire mvaruganda, kandi igira uruhare mu gukwirakwiza gazi n’amazi, no gushyigikira, gutwikira no kurinda katalysts.
2) Ishobora kandi gukoreshwa mu itanura rishyushye n'ibikoresho bihindura ubushyuhe mu nganda z'ibyuma.
