Abstract

The relationship between particle size of hydro-thermally synthesized barium titanate powders (BT01, BT02, BT03, BT04, BT05) and the powder properties was investigated by means of particle size, specific surface area, zeta potential, XPS, XRD and SEM. Particle size determined by laser light scattering is closely related with specific surface area and the tetragonality (c/a) obtained from XRD. The specific surface area of the samples inversely decreased with increasing particle size except BT03 powder. BT03 sample showed higher surface area than BT04 sample of equivalent particle size, which was attributed mostly to the agglomeration of particles in terms of SEM image and XRD analysis. Zeta potential increased with increasing particle size with the exception of BT02 and BT03 which showed larger minus value of zeta potential in comparison with other BT powders. Beta potential results of BT02 and BT03 are considered to be related with the dissolution of $Ba^{2+}$ ion in these powers which was examined by XPS.

수열합성법에 의해 제조된 티탄산바륨 (BT01, BT02, BT03, BT04, BT05)의 입자크기와 분체특성과의 상관관계를 비표면적, 제타전위, XPS, XRD 및 SEM에 의해 조사하였다. 레이져광산법에 의해 측정된 입자의 크기는 비표면적과 XRD를 통해 결정된 격자이방성과 밀접한 관계가 있음을 보였다. 분말의 비표면적은 입자의 크기가 증가함에 따라 감소하였으며, BT03 시료는 동일한 입자크기의 BT04에 비하여 큰 비표면적을 보였으며, 이는 입자들의 응집에 기인하는 것으로 SEM사진 및 XRD 분석을 통하여 밝혀졌다. 입자의 크기가 증가함에 따라 제타전위는 증가하는 경향을 보였으며, BT02와 BT03 분말은 다른 분말에 비하여 제타전위가 큰 음의 값을 나타내었다. XPS 분석결과 분쇄시 티탄산바륨과 물 사이의 반응에 의한 $Ba^{2+}$ 이온의 용출과 관련이 있는 것으로 분석되었다.
