Product Advantage

The followings are important for the use of BaTiO3, both for the bulk device and substrate:
1.The tetragonal BaTiO3 single crystal (the useful phase for both photorefractive effect and substrate) will change the phase when its temperature is lower than 13℃ or higher 125℃, so it is necessary to keep its temperature in the safe range during its using, storage and transportation.
2.The extra force such as compacting, cracking will cause a phase transition.
3.Poling is needed for (001)orientation substrate, while is not necessary for (100)、(110)、(111)orientations.
4.Normally the maximum size for BaTiO3 substrate is 10x10mm; the thinnest thickness is 0.3mm.

Product application

Barium titanate crystal substrates have excellent photorefractive properties, high self-pumped phase conjugate reflectance and two-wave mixing (optical amplification) efficiency, and have huge potential application prospects in optical information storage.They are also important substrate material.
Barium titanate crystal substrates are used in the following applications:
– Optical information storage
– Uncooled sensors for thermal cameras
