It is so incredibly soft that it can easily be cut with a knife, like an [[alkali metal]]. It is very similar to [[zinc]] in [[chemical properties]], but it is less reactive with [[acids]] than zinc.<ref name=news>[http://www.eoearth.org/article/Cadmium Properties] Unknown author, International Cadmium Association, Accessed December 1st, 2010.</ref> | ||
Cadmium is very resistant to [[corrosion]], particularly in acidic and [[seawater]] [[environments]]. It has a low melting [[temperature]], good [[electrical]] and [[thermal]] [[conductivity]]. Compounds containing cadmium possess an amazing resistance to high stress and high temperature. They also lower [[ultraviolet light]] degradation of certain [[plastics]]. Some cadmium [[electronic]] compounds exhibit [[semi-conducting]] properties, so they are used in [[solar cells]] and many electronic appliances. Cadmium [[pigments]] produce intense yellow, orange and red colors, and are widely used in [[plastics]], [[glasses]], [[ceramics]], [[enamels]] and [[paints]].<ref name=Cadmium>[http://www.cadmium.org/ Cadmium] Unknown author, International Cadmium Association, Accessed December 1st, 2010.</ref> | Cadmium is very resistant to [[corrosion]], particularly in acidic and [[seawater]] [[environments]].
