The objective of present study is to understand how the synthesis parameters influenced the composition and structure of the particles of material. Since a most distinctive feature of fine MgTiO 3 material is the tendency to exhibit a XRD-cubic structure at room temperature. The relationship between the XRD structure and the size for this processing method is reported. Variation of intensity with different composition of material has also been reported.

INTRODUCTION In recent years, TiO 3 has been well known as a semiconductor [1] with photocatalytic activities and has a great potential for applications such as environmental purification. The performance of the material (TiO 3 ) affected by the size of the particles [2]. TiO 3 is mainly applied as pigments, adsorbents, catalyst supports, filters, coatings, photoconductors, and dielectric materials [3]. Thus particle size plays a great role. Zinc oxide (ZnO) [4] has a relatively large energy band gap ( ~3.3 eV) at room temperature [5]. The band gap of zinc oxide may be increased to nearly 3 – 4 eV by alloying it with magnesium oxide. Zinc oxide is commonly used in laser diodes and light emitting diodes (LED). Some optoelectronic [6] applications of ZnO overlap with that of GaN, which has a similar bandgap (~3.4 eV at room temperature). Magnesium (Mg) powder (flash powder) [7, 8] was used as a source of illumination in the early days of photography. All the above base materials are taken in different proportion by weight and ground properly in order to make a fine homogeneous mixture. Now different compositions of materials (MgTiO 3 with ZnO) [9] are analyzed by X- ray diffraction (XRD) [10] and comparative study will be observed with the obtained XRD pattern. Magnesium titanate (MgTiO 3 ) has potential applications such as high frequency capacitors, chip capacitors, and temperature compensating capasitors [11], resonators, filters, antennas for communication, radar and direct broadcasting satellite [12]. Data on particle size can be obtained by X-ray diffraction (XRD) technique as the particle size is related to the diffraction peak broadening. II. MATERIAL AND EXPERIMENTATION DETAIL For the preparation of the mixed system, high purity Mg, TiO 3 and ZnO are taken in different proportions. The three base material pure magnesium (Mg), pure titanium oxide (TiO 3 ) and pure zinc oxide (ZnO) are taken in the powder form. All the three base material are taken in different proportion by weight. These proportions are ground properly in order to get homogeneous mixture. The homogeneous mixture is then fired in a cylindrical furnace (Muffle furnace) at 600 0 C to 800 0 C in controlled atmosphere. The heated material is then cooled and again grounded in order to make a fine mixture in the form of powder. In our experiment, we have prepared two samples having different proportions. The first sample is made by taking 40% Mg, 40% TiO 3 and 20% ZnO named as MTZ1 and second sample is made by taking 46% Mg, 46% TiO 3 and 8% ZnO named as MTZ2. XRD measurements were performed on the Bruker D8 Advance diffractometer operating in the reflection mode with Cu-K α radiation (35 kV, 30 mA) and diffracted beam monochromator, using a step scan mode with the step of 0.075° (2θ) and 2.5 s per step at room temperature 25 0 C.
