Abstract
Single crystal fibers of CaTiO3 have been grown by the Laser Heated Pedestal Growth (LHPG) method up to several cm in length with diameters of 500–700 μm. The crystals, characterized by X-ray diffraction analysis, have the distorted orthorhombic perovskite structure. Dielectric constant, dielectric loss and temperature coefficient of resonant frequency along the [101]o and [010]o (o means orthorhombic unit cell) direction of the crystal were investigated over the temperature range from −250°C to 100°C. The results of thermal expansion measurements up to 850°C reveal no unusual behavior associated with phase transitions. One of the modes of twinning reported by Bowman from optical analysis is confirmed by optical microscopy.
