PROCESSING OF SODIUM--POTASSIUM NIOBATE CERAMICS.

Description: Sintering studies of undoped (Na{sub 0.5}K{sub 0.5})NbO{sub 3} and the same material doped with 1/2, 1, 2, and 4 mole percent BaO and 2 mole % B{sub 2}O{sub 3} were made. The persistence of a second phase after calcining to form the compound led to a study of reactions occurring during calcination. The calcining of sodium-potassium niobates involves the formation of an intermediate compound (the second phase) and its subsequent reaction with sodium oxide and potassium oxide to form (Na{sub 0.5}… more
