Combustion process and heating applications

This study presents the process of synthesizing BiFeO3 by the Gel – Polymer combustion method under optimal condition, selected through the investigation of influencing factors and the characteristic of materials, including the Gel formation temperature (80°C), the molar ratio of Bi/Fe (1/1), the molar ratio of the mixture metal/PVA (1/3), pH=1, and the sample is heated at 500oC for 2 hours.

EVOLUTION OF SERVO DRIVES The word ‘‘servo’’ is a learned borrowing from Latin where it meant ‘‘slave.’’ Industrial servos had their real beginning during World War II. Some applications were in military gun control and steering control. The evolution of speed and positioning drives since the war is shown in Figure 1.
