Synthesis, Sintering and Dielectric Properties of Nano Structured High Purity Titanium Dioxide
High purity nanosized titanium dioxide (TiO2) powders were synthesized by precipitation method using Ti(IV)-isopropoxide as starting material. Well-crystallized and phase pure anatase T1O2 powders with a particle size about lOnm can be obtained by calcination of (reeze-dried precipitates at 400°C. The sintcrability of powders calcined at 400°C and 700°C were compared with commercial TiO2 powders with similar particle size. The electrical and dielectric properties of the TiO2 bulk samples sintered at various temperatures were measured and correlated with the microstructural development.
