A2TinO2n+1 crystal alkali metal titanate (n=3 or 6, A=Na, K, Li) belongs to monoclinic system. Titanate n=3 or 4, (Ti3O7) 2- layer is alkali metal ions (Na+, K+) together, a layered structure, the layered structure makes it has very strong cation exchange and adsorption properties, especially for heavy metal ion exchange and adsorption, showing its unique performance.

Alkali metal titanate can be used to transfer the dielectric resonator ion exchange, ceramic capacitors, microwave oscillator, band, plastic reinforcer, oxygen electrode, insulating material, potentiometer sensor etc.. Alkali metal titanate and water titanate Yandu for N type semiconductor, display light excellent catalytic activity. Titanate is often used as the induction body titania based materials, in order to increase the ion exchange reaction rate or to the material properties of transition metal doped with the unique.

According to reports, foreign using three sodium titanate to deal with the heavy metal cesium, strontium, uranium and other heavy metal ions, the effect is very good, and can be recycled.

The other method is synthesized by chemical and thermal stability of three sodium titanate synthesis melting method above, and more convenient for nuclear waste disposal field. Because the synthesis of three sodium titanate itself high hardness, can be directly made into required size of particles, filling to exchange column, won't appear dispersion phenomenon. But large exchange capacity, regeneration, its performance is almost not change. The company is the sodium titanate crystal whisker synthesized by melting method, can be used directly to the nuclear waste disposal field.

Cation four potassium titanate whisker is also very good performance of the exchange and adsorption material, adsorption and ion exchange effect in some relatively weak, can and three sodium titanate whisker segment or mixed use, so that the heavy metal cations (containing radioactive nuclear waste) exchange and adsorption properties of higher.
