Abstract

Utilizing NaF as an internal standard and MgO as a diluent, quantitative evaluation of the amount of rutile can be obtained by x-ray diffraction of beach sands with a Geiger detection method. The percentage obtained by the x-ray method was checked with chemical determination of TiO 2 content and found to be in good agreement. Beach sand from Moana, South Australia, was used for the investigation.
