In its elemental form, copper has a red-orange metallic luster appearance. Of all pure metals, only silver has a higher electrical conductivity.The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus." Cyprus, a Mediterranean island, was known as an ancient source of mined copper.

Properties Chemical. Copper chromite is of greatest interest to the home chemist as a catalyst, such as in the synthesis of pyridine from niacin.Like Raney nickel, it is used in hydrogenation reactions in organic chemistry.. Physical. Copper chromite typically appears as a dusty black or green-black powder.

Copper is used widely in industry, because of his good thermal conductivity and mechanical properties. Copper is a relatively noble metal. Nevertheless, it reacts easily in ordinary environments containing oxygen. Thus, the study of its corrosion inhibition has attracted much attention.

Dec 22, 2000· Basic Black - Infrared Reflectance and Accumulated Heat To appear black, a pigment must absorb practically the entire spectrum of visible light. During the absorption process, light energy is converted to heat energy, causing the temperature of the surface to rise. Two of the most extreme examples of this are carbon black and copper chromite.
