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
Certain metal oxides like `VO_(2), VO, VO_(3)` and `TiO_(3)` show metallic or insulating property depending upon temperature, As temperature varies metallic or insulating property varies. This is due to variation in energy gap between conduction band and valence band.
