Question

Non - oxide ceramics can be

Options

A.B4C
B.SiC
C.Si3N4
D.All of these

Solution

Ceramics are inorganic, non-metallic, solid minerals. They come in a variety of forms,including silicates (silica, SiO2 with metal oxides), oxides (oxygen and metals), carbides (Carbon and metals), aluminates (alumina, Al2O3 with metal oxides)and nitrides.
The given ceramicsare B4C (carbides), SiC (Carbides), Si3N4 (nitrides) and thus, none of these is an oxide. All of these are nonoxide ceramics.
