which of the following oxides behaves as conductor or insulator depending upon temperature ?

A

TiO

B

`SiO_(2)`

C

`TiO_(3)`

D

`MgO`

Text Solution

Verified by Experts

The correct Answer is:
C
`TiO_(3)` behaves as conductor or insulator depending on temperature because of variation of energy gap between valence band and conduction bond with the variation of temperature.
