Sandwich texture and its effect on the electrophysical properties of lanthanum borogermanate based glass ceramics
Source abstract
Abstract
It is established by means of x-ray diffraction and electron microscopy that in La 2 O 3 - B 2 O 3 - GeO 2 glasses a lanthanum germanate La 2 Ge 2 O 7 film texture up to 5 μm thick, under which forms needle-like texture of stillwellite-like LaBGeO 5 possessing pyroelectric properties is formed in the surface layer on contact between the glass and a corundum substrate or under a load during heat-treatment in a wide temperature range. The temperature dependences of the dielectric and pyroelectric properties of the samples with La 2 Ge 2 O 7 - LaBGeO 5 - La 2 Ge 2 O 7 sandwich structure and ground samples containing only a stillwellite-like phase are studied.
