Studying the Structural Changes of NiSb2O4 by Temperature Using Sol-Gel Method

Abstract

The research aims to prepare NiSb₂O₄ system and study its structure and characteristics by Sol-Gel method in aqueous solutions and using CH₃COOH acid as an organic stabilizer. The mixture was drained for three hours to get rid of water, and grind it to powder and sintered it at various temperatures for two hours. The structural changes were compared to Differential Thermal Analysis (DTA) schemes. This showed that the temperature of dewatering is 125.67°C and the temperature of dewatering of removal the other organic is 326.18°C.The X-rays results showed that the dual system is formed at 700°C and the crystals are growed clearly by increasing temperatures with sharp peak till 1100°C. The system starts to disintegrate to the initial oxides. Therefore, the composite at low temperatures and high thermal and mechanical specifications was attended. It was noted that the installer accelerated the formation at 700°C and the growth of crystals becomes more quickly.
