Non-oxide ceramics can be

A
$B_4C$
B
$SiC$
C
$Si_3N_4$
✓
All of these

✓

Answer

Correct option: D.

All of these

d
Ceramics are inorganic , non-metallic, solid minerals. They come in a variety of forms, including silicates (silica, $SiO_2$ with metal oxides), oxides (oxygen and metals), carbides (carbon and metals), aluminates (alumina, $Al_2O_3$ with metal oxides) and nitrides.

The given ceramics are $B_4C$ (carbides), $SiC$ (carbides), $Si_3N_4$ (nitrides) and thus, none of these is an oxide . All of these are nonoxide ceramics.
