The phase, densification, microstructure, mechanical and dielectric properties of HA-BST composites sintered at 1350 °C were investigated. The HA-BST composite showed an increase in densification, Vickers hardness, Young's modulus and fracture toughness with maximum value as 3.42 g/cm<sup>3</sup>, 5.01 GPa, 161.70 GPa, and 1.48 MPa m<sup>1/2</sup>, respectively. The average grain size was decreased from 12.09 μm for a reference HA sample to 1.14 μm for the 30 wt% BST in HA-BST composites. The dielectric constant as a function of temperature and frequency tend to increase with increasing BST contents. 2018-09-04T10:10:21Z 2018-09-04T10:10:21Z 2015-01-01 Journal 02728842 2-s2.0-84937512713 10.1016/j.ceramint.2015.03.205 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84937512713&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/54267 |
