Title: Effect of STAC on Structure of Biotite when Biotite Transform to Hydrated Ba-Mica

Fourier transform infrared spectroscopy and powder X-ray diffraction spectroscopywere were used to characterize the obtained samples to reveal the changes of interlayer spacing and basal spacing. The results showed that STA + could not enter into the interlayer spacing of biotite but enter into that of hydrated Ba-mica and mixing mica. Almost all basal spacing of Ba-mica and mixing mica were increased to 2.8nm.Read More
