Jan 05, 2009 Therefore, when exposed to water vapor at 1400C, the remaining cristobalite will react with water according to Eq. (1), causing weight loss for Sc 2 O 3 2SiO 2 sample in the initial stages. Because the ratio of Sc 2 O 3 to SiO 2 in Sc 2 O 3 2SiO 2 sample is 1:2, the existence of free silica implies the Sc 2 O 3 is also in the sample.
