Abstract.A study on the fabrication of Iron Titanium Oxide (Fe2TiO5) ceramics for negative temperature coefficient (NTC) thermistors has been carried out, in order to know the effect of sintering temperature on the electrical characteristic of 1.0 % mole Nb2O5 doped Fe2TiO5 ceramics.These ceramics were made by mixing commercial powders of Fe2O3, TiO2 and Nb2O5 with proportional composition to produce Fe2TiO5 based ceramic. The raw pellet was sintered at 1000 oC, 1100 oC and 1200 oC temperature for 2 hours in air. Analysis of the microstructure and crystal structure were performed by using a scanning electron microscope (SEM) and x-ray diffraction (XRD) respectively. XRD spectra showed that the crystal structure of all ceramics of Fe2TiO5 made at various sintering temperatures are orthorhombic. The SEM images showed that the grain size of pellet ceramics increase with increasing sintering temperatures. From electrical resistances data that was measured at temperature 30-300 0C, it is found that the value of thermistor constant (B), activation energy (Ea), thermistor sensitivity (α) and room temperature resistance (RRT) decreases with respect to the increasing of sintering temperature. The fabricated Fe2TiO5 ceramics have thermistor constants (B = 6394-6959 K). This can be applied as temperature sensor, and will fulfill the market requirement.

INTRODUCTION

Negative Temperature Coefficient (NTC) thermistor has been widely used around the world today, due to its capability used in various fields of electronics, such as thermometer, electric current limiter, water flow sensor, and pressure sensor [1, 2]. The NTC thermistor is generally made of ceramic having structure of spinel of AB2O4 where A is the ion occupies tetrahedral position and B is the ion occupies octahedral position [3, 4]. Fe2TiO5 ceramic is one of some ceramics that can be applied for NTC thermistor. The thermistor may be produced in the form of disk/ pellet or thick film. Here, the object of study is the pellet thermistor.

In this work, a study on fabrication of pellet thermistor based on Fe2TiO5 with sintering temperature variationwas performed. The effect of sintering temperature on the characteristics, especially the electrical characteristics, of the Fe2TiO5 pellet ceramics for NTC thermistor was discussed. Fe2TiO5 is one of semiconductor ceramics used as based material for main components fabrication of NTC thermistor as temperature sensor. The composition of mineral Fe2TiO5 is belong to pseudobrokyte group where the general formula of this compound is X2YO5 with octahedral in both side, X and Y. Generally, Fe2TiO5 has been mostly used for gas sensor, non linear optic, magnetic, catalyst, and microelectronics [5, 6]. Since Fe2TiO5 actually has semi-conductivity, it is very capable to use Fe2TiO5 for NTC thermistor as based material. Thermistor constant B is a quantity which determine typical characteristic of thermistor corresponding to electrical resistance changes with temperature. The larger thermistor constant lead to better thermistor quality. Many works and studies have been conducted by researchers to enhance thermistor constant B and thermistor sensitivity α. They have studied the effect of sintering temperature to typical characteristic of Fe2TiO5-based ceramics. The research of NTC thermistor for high temperature has been
