Titanium dioxide -- abbreviated TiO2 -- has a high dielectric constant. It polarizes readily when exposed to an electrical current. Because of this quality, TiO2 appears as a solid ceramic dielectric in applications like capacitors or integrated circuits. Also known as anatase, rutile or sintered titania, TiO2 makes certain kinds of sensors and electronic catalyses possible. In order to use TiO2 as a dielectric, take into account both its chemical and physical properties.
Instructions
-
-
1
Counter the high conductivity of refined TiO2, for example, by combining it with another insulator.
-
2
Subject the sintered titania to electrical current, and allow it to polarize that current. This stage takes advantage of the dielectric properties of TiO2.
-
-
3
Harness the polarized current, for use in photocatalysis, light sensors or other electronic applications.
