METHOD FOR PRODUCING MONOCRYSTALS OF LANTHANUM AND GALLIUM SILICATE

摘要

The present invention pertains to the chemical techniques used in the field of oxide-based composite materials for growing piezo-electric monocrystals that essentially consist of lanthanum and gallium silicate La3Ga5SiO14. The lanthanum and gallium silicate crystals are grown according to the Chokhralskiy method on a seed crystal having an orientation of <01.1>, <02.1>, <02.3> and <03.2>. The melt mixture is obtained in two steps according to a method of high-temperature self-propagating synthesis.
