Polyacrylonitrile (PAN) matrix composites dispersed with potassium sodium niobate (KNN) with volume fraction of 0–30% were prepared by ball milling followed by hot pressing. Density of composites followed the rule of mixture. Good dispersion of KNN particles in PAN matrix was confirmed using SE...detailed
Sodium niobate thin films doped with manganese (NN), and NN films modified with 5 or 10 mol % calcium zirconate (CZ) on platinized silicon substrates were prepared by chemical solution deposition. The 250-nm-thick films crystallize in a perovskite phase with fine, equiaxed grains. The NN films e...detailed
Niobium oxide is known for its biocompatibility; however it lacks on bioactivity. Sodium is one of the essential elements required for the formation and maintenance of bone. In this present study, we focus on improving the bioactivity of niobium oxide by incorporating sodium ions and obtaining n...detailed
Dense and stoichiometric NaNbO3 ceramics were difficult to be prepared by conventional sintering methods because Na2O easily volatilized at elevated temperature. In this work, the volatility of Na2O was suppressed by applying an electrical field assisted sintering method. Flash sintering was pre...detailed
