The image after thresholding still contained undesirable noise and images out of focus, which can be the source of significant error in the analysis (Fig. By using the thresholding color process, we could select the different threshold methods in this study. Figure 2(a) shows an original SEM image used for the analysis. Flowchart of the image processДЇigure 2 (a-d) show the images transformed by the image analysis. So the other thresholding methods in the analyzing tool of ImageJ are applied for separating easily the each particle boundary at the particle-to-particle cross-over areas.ДЇigure 1. However the particle boundaries at particle-to-particle cross-over area are difficult to be identified from the SEM image. The boundary can easily be detected from binary images or other types, which were obtained from the thresholded SEM images. In the second step, the boundaries of each grain on the image were detected. Furthermore the detail and required measurements are set up in this step. In the first step, the measure scale is set that is suitable with the 2D SEM image. The analysis was carried out in two steps. Figure 1 shows a flow chart of the image analysis process developed within ImageJ. Surface microstructure was observed by scanning electron microscopy (SEM, JSM-5610LV, JEOL, Japan) (Fig. Sintered samples after chemically-etching were cleaned by ultrasonic cleaner. Sintering was carried out at the temperature of 1450в„ѓ for 4h. After the second milling, the obtained powders were pressed into disks specimens with a diameter of 12mm and a thickness of 1.2 mm only by uniaxial pressing with a pressure of 100MPa. The mixtures were ball-milled in ethanol for 20h, then dried. The obtained powders were dried in an oven and then calcined at 1250в„ѓ for 3h. The raw materials with high purity (> 99%) of BaCO 3, CaCO 3, ZrO 2, TiO 2 were weighed and mixed in a centrifugal mill, as well as wet-homogenized with ethanol for 20h. Sample Description and Image Analysis Processing with ImageJ A conventional ceramics fabrication technique was used to prepare Pb-free ceramics (Ba 0.7Ca 0.3)TiO 3-0.48Ba(Zr 0.2Ti 0.8)O 3. The type of piezoelectric materials chosen for research was Pb-free piezoelectric materials (Ba 0.7Ca 0.3)TiO 3-0.48Ba(Zr 0.2Ti 0.8)O 3 (48BZT-BCT). However, in this study, we concentrate on two of the most significant properties and necessary in measuring - particle size distribution and shape analyzing. Depending on the requisition of research, some or lots of parameters of materials could be studied, e.g. The present paper describes an investigation of the 2D structure analyzing from SEM image using ImageJ program. However the programming is not possible in an easy way as well as its copyright. allow performing the 2D structure images and providing the processing and analysis features.

Parallel to this process, numerous commercial software exist such as Amira, Comsol Multiphysiscs, LINCE etc. These techniques enable a better resolution but also permit to obtain true data. Last decade has seen the development of major microscopic techniques such as electron microscopy, scanning probe microscopes and etc. However, the extremely small boundary between the particles and random orientation make the measurement of their size very difп¬Ѓcult.

In addition, measuring particle size distributions and understanding how they affect the properties of materials can be critical to the success of many manufacturing businesses.

The particle size and measuring particle size distributions is one of the most important structural characteristics relating to process efficiency, and material quality. In order to analyze and evaluate the preeminent properties of the new materials, some parameters of the structure of the materials are proposed for research. To date lots new piezoelectric materials are researched and widely used for various applications such as actuators, sensors, sonar transducers, accelerometers, resonator, frequency control devices, filters and etc. Introduction After discovered at 1950, lead zirconate titanate ceramics have enormously been studied because of their excellent piezoelectric properties.
