Just a simple finely sliced cabbage, onion, carrot affair with a squeeze of lemon and spoonful of mayonnaise (Hellmans - I don't think I can be really bothered making my own mayonnaise).
Erbium's everyday uses are varied. It is commonly used as a photographic filter, and because of its resilience it is useful as a metallurgical additive. Other uses: 1  Used in nuclear technology in neutron-absorbing control rods. 2  When added to vanadium as an alloy, erbium lowers hardness and improves workability.rbium is a chemical element in the lanthanide series, with symbol Er and atomic number 68.
Barium was identified as a new element in 1774, but not reduced to a metal until 1808 with the advent of electrolysis. Barium has only a few industrial applications. The metal has been historically used as a getter for vacuum tubes.It is a component of YBCO (high-temperature superconductors) and electroceramics, and is added to steel and cast iron to reduce the size of carbon grains within the microstructure of the metal.arium has only a few industrial applications.
