#"Silicon carbide versus aluminum nitride versus calcium carbide"#
#"versus aluminum carbide"#...........?

Explanation:

Of all of these material, #"silicon carbide"# should be the most inert, i.e. the least reactive. Silicon carbide has been used for drill bits and bullet proof vests because of its hardness. Why don't they use diamond instead of silicon carbide?

In fact all of these materials (except perhaps for #"calcium carbide"#, which formed the original miners' lamp) are now extensively used as solid-state materials.
