Rabewa da halayen gaba ɗaya na manyan tubalin alumina

Za’a iya rarraba maɗaukakin alumina mai ƙarfi bisa ga ingancin matakin, wanda za’a iya raba kusan zuwa nau’i hudu: akwai tubalin alumina masu girma na matakin farko, tubalin alumina masu girma na biyu, tubalin alumina mataki na uku da na musamman. – matakin high-alumina tubalin. Dangane da ma’aunin ma’auni na masana’antu, alamomin sinadarai Wadanda ke da abun ciki na aluminum ≥55% sun zama tubalin alumina masu daraja na uku, waɗanda ke da abun ciki na alumini na sinadarai ≥65% sun zama tubalin alumina mai daraja na biyu, da waɗanda ke da alamar aluminum. abun ciki ≥75% zama farkon-aji high-alumina tubalin. Fihirisar sinadarai ta ƙunshi aluminum. Adadin ≥80% ya zama babban bulo na alumina.
