About Cobalt Chromium Sponge

Cobalt Chromium SpongeCobalt Chromium Sponges have high porosities- 75-95% of volume is empty space. Cobalt Chromium 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 Chromium 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 Chromium 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 Chromium sponges are used in a wide variety of applications potentially including heat exchangers, energy absorption, flow diffusion, and lightweight optics.

Chromium Bohr ModelThe number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Chromium was first discovered by Louis Nicolas Vauquelin in 1797. It was first isolated in 1798, also by Louis Nicolas Vauquelin. The chromium atom has a radius of 128 pm and a Van der Waals radius of 189 pm. In its elemental form, chromium has a lustrous steel-gray appearance. Elemental ChromiumChromium is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it tranforms into a paramagnetic solid. The most common source of chromium is chromite ore (FeCr2O4). Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color.

Cobalt Bohr ModelThe number of electrons in each of cobalt's shells is 2, 8, 15, 2 and its electron configuration is [Ar] 3d7 4s2The 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."
