Earlier high temperature structure analysis by neutron powder diffraction suggested that Si vacancies were created when Ti3SiC2 was heated. A specimen that was heated to 906 degrees C overnight was later examined at room temperature. For this subsequent room temperature data set refinement of the Si site occupancies in the Ti3SiC2 structure did not support the hypothesis that Si vacancies were being created when the sample was held at elevated temperatures in a vacuum furnace.
