This structure yields a more compact beta-quartz-type phase that eventually stabilizes it in wider pressure range than pure SiO2. Raman spectroscopy allows to unravel at least two pressure-induced structural phase transitions at about 6 and 15 GPa that could not be previously revealed by x-ray ...

[9] the main crystalline phase in a LMAS glass-ceramic prepared by the solid state method are β-quartz solid solution (Li2Al2Si3O10), lithium silicate (Li2SiO3) and forsterite (M2P-16ASiO4). Li et al. [12] also reported that the addition of MgO facilitates the phase transformation...

In heterogeneous catalysis, olefin oligomerization is typically performed on immobilized transition metal ions, such as Ni2+ and Cr3+. Here we report that silica-supported, single site catalysts containing immobilized, main group Zn2+ and Ga3+ ion s

very different from that in the magnesium alumosilicate system. In the latter, comparatively large ZrO2crystals are formed which do not exhibit spherical or cuboid shape. The tiny ZrO2crystals, also observed in the MAS system are formed at the growth front of quartz during onward crystallization44...
