Characterization of LiNbO3 powder prepared by citrate gel method

Lithium niobate powder (LiNbO3) were synthesized by citrate gel method using LiNO3, Nb2O5, citric acid and HF as starting materials. LiNO3 was dissolved in distilled water that activated into LiOH. Nb2O5 was dissolved in minimum amount of HF at 37°C for 20 h. that activated into NbF5. Then citric ac...
