| http://www.w3.org/ns/prov#value | - Inorganic salts, such as chlorides and carbonates of sodium, potassium and barium, which are relatively stable at temperatures considerably above their respective melting points, are fused in large metallic or refractory containers at temperatures up to about 700oC. At higher temperatures, heat-resisting Fe-Ni-Cr alloy pots or refractory containers should be used.
