Aug 01, 2014· As shown in Fig. 1, the major phase in the samples of untreated and slag oxidized at 600 °C was M x Ti 3 -x O 5 (0 ≤ x ≤ 2). However, as the roasting temperature increased to 800, 1000 and 1200 °C, rutile becomes the major phase in the slag.Despite this, there was still a large amount of M x Ti 3 -x O 5 (0 ≤ x ≤ 2) present. These results …
