抛光具有2SrO中心点TiO2中心点2.75 SiO2组成的玻璃样品，随后用石墨或氧化铝粉末覆盖，最后在970 ℃下退火20小时以诱导表面结晶。利用X射线衍射（XRD）和电子背散射衍射（EBSD）分析了表面处理对生长过程中的择优晶向的影响。此外，表面处理对压电d（33）值的影响进行了描述，并参考抛光样品退火没有预先的表面处理。
Glass samples with the composition 2SrO center dot TiO2 center dot 2.75 SiO2 were polished, subsequently covered with graphite or alumina powder and finally annealed at 970 degrees C for 20 h in order to induce surface crystallisation. The effect of the surface treatment on the preferred crystal orientations during growth into the bulk is analyzed using X-ray diffraction (XRD) and electron backscatter diffraction (EBSD). Furthermore, the effect of the surface treatment on the piezoelectric d(33)-value is described and referenced to polished samples annealed without previous surface treatment.
