Chengetedzo yealuminium crucible

Corundum crucible inogona kushandiswa kunyunguduka uye kunyunguduka kwemamwe alkaline fluxes, asi tembiricha haifanirwe kunge yakanyanya kukwirira, uye nguva yacho inofanira kunge ipfupi sezvinobvira. Mune zvimwe zviitiko, inogona kutsiva nickel uye platinum crucibles, asi kuyerwa kwealuminium nealuminium kunovhiringidza kuyerwa. Haikwanise kushandiswa pasi.

What is the difference between low temperature alumina and high temperature alumina

Zvese zviri zviviri zvakaderera-tembiricha alumina uye yakakwirira-tembiricha alumina ndeye alumina, uye kune akawanda makristasi mafomu. Shanduko yetembiricha inogona kuona shanduko pakati pezvinhu, uye yakaderera-tembiricha alumina inogona kushandurwa kuita α-crystal alumina mushure mekukwirira-tembiricha calcination.

High temperature alumina is white powder, which is calcined by alumina. In reality, high-temperature alumina is mostly used, and low-temperature products may be added with other trace elements.
