Abstract
It was realized that MC-XRD is useful for phase analyzing of inclusions in crystals because it can focus the X-Ray beam to the small particles sized dozens of $\mu\textrm{m}$ with high S/N ratio. By using this MC-XRD, needle-like inclusions which are seen generally in corundum crystals known as rutile was found to be the iron titanium oxide and iron oxide which has the chemical composition of $Fe_2TiO_4,\; Fe_2TiO_5,\; Fe_2O_3$respectively
