METHOD OF PRODUCTION OF PYRO-ELECTRICAL VITRO-CRYSTALLINE MATERIAL Russian patent published in 2006 - IPC C03C10/02 

FIELD: manufacture of pyro-electric vitro-crystalline materials widely used in modern technology (remote thermal monitoring of production processes, thermal monitoring of environment).

SUBSTANCE: proposed method of production of pyro-electric vitro-crystalline material includes melting of charge of the following composition, mole-%: La₂O₃, 23-27; B₂O₃, 23-27; GeO₂, 48-52 in platinum crucible, molding the melt for obtaining glass plates and crystallization of glass plates performed at temperature of 920°C-980°C in temperature field gradient of 50-100°C/mm continued during 2-8 h. Specimens thus made are characterized by the following parameters: γ=3.5-4.5 nC/cm²K, ε=10-11. γ/ε ratio is approximately 0.35 nC/cm²K.

EFFECT: enhanced efficiency.
