Microstructure Control of Potassium Niobate Porous Ceramics and their Sensor Properties

Abstract:

Porous potassium niobate (KNbO₃, KN) system ceramics were prepared by spark plasma sintering (SPS) method using carbon black (CB, 5 μm). First, the powders of raw materials were mixed in ethanol by ball milling, and then calcined. Obtained KN powders with CB were sintered by SPS in argon atmosphere. Their piezoelectric properties were measured and a relationship between porosity, pore size, and sensor properties was studied. It was found that d₃₃ increased as pore size decreased. Thus, pore size was important for the improvement of value of g₃₃/ρ.
