Alumina Tabeellaha ah ee Qalalan ee Ramming Mass Alumina Tabeeleed Lafeeyay oo loogu talagalay Walxaha Ceyriin
Sharaxaadda Alumina ee Shaxda ah
Korundum tabular, sidoo kale loo yaqaanaluminium tabular ah oo isku dhafan, waa nooc saafi ah oo alumina ah (Al2O3) kaas oo si gaar ah loo farsameeyay si uu u yeeshoshaxda gaarka ah, ama fidsan, qaab.Waxaa lagu soo saaraa sinteering (kuleyl la'aan dhalaalid la'aan) budada alumina heerkeedu sarreeyo ee heerkul ka sarreeya 1900 ° C, taasoo keenaysa in qaybaha alumina ay koraan oo ay sameeyaan kiristaalo waaweyn, fidsan, saxan u eg.

| Isticmaalka: Corundum tabular waxaa si ballaaran loo isticmaalaa in-waxqabadka sare refractory beeraha eebirta, shubista, kiimikooyinka petrochemicals, leben la neefsan karo, dahaarka saqafka, kabka, qaybo hore loo sii diyaariyey, ceramics iyo beero kale.Waa walxo ceeriin ah oo aad u fiican.Corundum tabular waxaa loo isticmaalaa sidaIsku-darka dib-u-celintawaxaa loo isticmaali karaa in lagu daro spinel, calcined alumina fir fircoon iyo walxaha xira sida sibidhka, dhoobada ama resin.Lebenka korundum ee nadiifka ah ee la diyaariyey waxay leeyihiin waxyaabo wasakh ah oo hooseeya (sida SiO2), cufnaanta sare ee sare iyo guryaha kulaylka wanaagsan, samaynta lebenka corundum Lebenku waxay u adkaystaan kulka, kiimikooyinka iyo waxyeelada dhismaha ee ay keento hawlgalka gaasifiers iyo foornooyinka kale ee warshadaha. | ||
