Title:
TELLURATE CRYSTAL, GROWTH METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/129962
Kind Code:
A1
Abstract:
A tellurate crystal, a growth method therefor, and a use thereof. The chemical formula of the crystal is MTe 3O 8 in which M is Ti, Zr and Hf; the tellurate crystal belongs to a cubic system and Ia-3 space group; the waveband of transmittance of the crystal is from visible light to infrared light; and the crystal has a transparency of greater than or equal to 70%. According to the growth method for the tellurate crystal, a flux method, a pulling method or a bridgman method can be used to grow the crystal. The tellurate crystal can be used as an acousto-optic crystal in the fabrication of optical modulation devices. The size and quality of single crystals of the tellurate crystal can satisfy practical uses.
