摘要：Glass-ceramics grown from a glass of the composition Sr₂TiSi_2.45O_8.9 (STS 45) are analyzed by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Oriented nucleation with the c-axes preferably perpendicular to the surface is detected. A very strong 001-texture is observed after only 10 μm of growth into the bulk, making this the first system in which an orientation preferred during nucleation prevails during growth into the bulk in glass-ceramics. Piezoelectric measurements are performed and d₃₃-values presented and discussed. The obtained results are critically viewed with respect to the two growth models describing Sr₂TiSi₂O₈ growth in glasses.
