About Cobalt Sponge

Cobalt SpongeCobalt sponges have high porosities- 75-95% of volume is empty space. Cobalt sponges are produced by injecting gas or mixing a foaming agent into molten metal which creates a froth that is stabilized by a high-temperature foaming agent. Cobalt sponges are cellular structures made with a large volume fraction of pores. Ceramic foam is often used for thermal insulation, acoustic insulation, adsorption of environmental pollutants, filtration of molten metal alloys, and as substrate for catalysts requiring large internal surface area. Cobalt Sponge is generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available. Sponge traits include low density, high stiffness, high energy absorbance, low thermal conductivity, low magnetic permeability, fire resistance, and sound dampening qualities. Cobalt sponges are used in a wide variety of applications potentially including heat exchangers, energy absorption, flow diffusion, and lightweight optics.

Related Elements

See more Cobalt products. Cobalt (atomic symbol: Co, atomic number: 27) is a Block D, Group 9, Period 4 element with an atomic weight of 58.933195. Cobalt Bohr ModelThe number of electrons in each of cobalt's shells is 2, 8, 15, 2 and its electron configuration is [Ar]3d7 4s2. The cobalt atom has a radius of 125 pm and a Van der Waals radius of 192 pm. Cobalt was first discovered by George Brandt in 1732. In its elemental form, cobalt has a lustrous gray appearance. Cobalt is found in cobaltite, erythrite, glaucodot and skutterudite ores. Elemental CobaltCobalt produces brilliant blue pigments which have been used since ancient times to color paint and glass. Cobalt is a ferromagnetic metal and is used primarily in the production of magnetic and high-strength superalloys. Co-60, a commercially important radioisotope, is useful as a radioactive tracer and gamma ray source. The origin of the word Cobalt comes from the German word "Kobalt" or "Kobold," which translates as "goblin," "elf" or "evil spirit."
