Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the oxygen in air or in water.

One example of RFC is solid oxide regenerative fuel cell.

As the heating continues, the nitrites finally decompose into a fragile mesh of solid oxides of very high melting point.

These include certain soft metals (indium, lead, silver, tin), polytetrafluroethylene, some solid oxides, rare-earth fluorides, and even diamond.

There are no neutral Mg atoms or condensed metal phases or solid oxides.

When it is electrolyzed, it makes a bright red solid, bismuth(V) oxide.

Fuel cells are characterized by their electrolyte material; the SOFC has a solid oxide or ceramic, electrolyte.

The ionic conductivity of the solid oxide is defined as follows:

Tellurium dioxide (TeO) is a solid oxide of tellurium.

The small amount of solid oxides are all that remain.
