- 論文の詳細を見る
Ba-deficient non-stoichiometric compositions of Ba_<5-x>Nb_4O_<15-x> (x=0 to 0.5) have been investigated for the purpose of improving microwave dielectric properties. While there was no significant variation in dielectric constant, variations in Q×f and TCF (temperature coefficient of frequency) values with the degree of Ba deficiency were prominent. Near zero TCF value was obtained for the composition of Ba_<4.77>Nb_4O_<14.77>. The apparent formation of a second BaNb_2O_6 phase for the Ba-deficient compositions was believed as responsible for the improved TCF. It was interesting to note that the second phase was present more preferably inside of the sample.
