TeO2 | Piezo-Electrical Crystal is an excellent acousto-optic (AO) crystal with high AO figure of merit, birefringence, good optical rotation, and slow propagation velocity along the  direction. The resolution of AO devices made of TeO2 crystals is several levels greater than others. It consists of yellow and white fine crystalline powder and when heated, it melts to a dark yellow. It is not water soluble, and the melting and boiling point is 733°C and 1260°C, respectively.
