Molten Salt Synthesis of the Barium Strontium Titanate Ba_1-XSr_XTiO₃ with KOH-KNO₃

Abstract:

The synthesis of Ba_1-xSr_xTiO₃ (BST) powders was attempted using KOH-KNO3 molten salt. The starting materials, Ba(NO3)2, Sr(NO3)2 ,TiO2,and the mixed salt of KOH-KNO3, were well-mixed. The mixture was heated at 300 to 500°C for 1 hour, and the product was thoroughly washed with de- ionized hot water. When the mixture containing excess TiO2 was used, single-phase BST powders with a particle size of 10~50nm were obtained.
