Evaluation of thermal testing and X-ray diffraction of Ka0,5Na0,5NbO3

The structure of perovskite-based material contained in the niobate and titanate. The fabric was a perovskite crystal structure having the formula ABO 3 . Ferroelectric and piezoelectric materials had a perovskite structure. This material could store an electric charge, which was good because of the polarization resulting in a material that was a dielectric. Unleaded piezoelectric material, K 0,5 Na 0,5 NbO 3 (KNN), was synthesized using reliable state methods. Synthesis was done by first setting up K 2 CO 3 , Na 2 CO 3 , and Nb 2 O 5 as a base KNN system. Studies cover X-ray diffraction, thermal analysis TGA-DTA and lattice parameter analysis. From the TGA-DTA analysis obtained for KNN calcination temperature at 700 0 C for 2 hours can produce a single-phase ABO 3 where A = (K, Na) and B = (Nb). Orthorhombic perovskite structure KNN material owned by P4mm space group with lattice parameters a = 3,572 Å; b = 3,570 Å; and c = 3,565 Å.
