A series of large size and high quality potassium tantalate(KTa3O)single crystals up to 31 mm×31 mm×40 mm,weighing as much as 247 g,were grown by the Czochralski method.

Nb2O5 liquor is added into the Ta2O5 to form standard solution,then carry out chromatographic separating on paper after series of treatment with potassium fluotantalate sample parent solution.

Determinated micro-sulfur of potassium fluotantalate, Sensitivity of combustion-conductance method is 0.

Study on tantalates photocatalyst for water splitting;

X-ray Diffraction Analysis of Tantalate Ba_5YTi_3Ta_7O_(30) andIts Dielectric Properties;

Structure and Dielectric Properties of New Tantalates Ba_2LnTi_2Ta_3O_(15)(Ln=Y,La);

Starting from the crystallographic data of lithium niobate and lithium tantalate crystals, structural characteristics and chemical bonding behaviors of both crystals are studied.

Because the thicker of crystal, the better for high-power laser bean shining, it s pivotal for lithium tantalate crystal to do some research with lithium tantalate crystal which has more than 1mm thickness in dectrical-poling.
