Dielectric constant & curie temperature of barium titanate

Item Code: SK205

Principle and Working:

Curie temperature is the transition temperature between the ferroelectric and the non-ferroelectric structures. In this experiment we Determine Dielectric Constant of ferroelectric ceramics at increasing temperatures.
Dielectric or electrical insulating material is understood as the material in which an electrostatic field can persist for long times. ... Layers of such substances are commonly inserted into capacitors to improve their performance, and the term dielectric refers specifically to this application.
