The natural occurrence of x-alumina in lateritic pisolites
Published online by Cambridge University Press: 09 July 2018
Abstract
Pisolites in the bauxitic laterites of Darling Range, Western Australia may contain up to 50% AI2O3, although no major Al-containing phases can be identified using standard X-ray diffraction techniques. These pisolites have been investigated using a range of techniques, and it has been demonstrated that Al is present in the form of x-alumina, a poorly crystalline form of A12O3. The x-alumina exhibits an indurating morphology and appears to have formed from a hydrated precursor.
