About Boron Carbide Sponge

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

The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s² 2p¹. The boron atom has a radius of 90 pm and a Van der Waals radius of 192 pm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808 and was first isolated by Humphry Davy later that year. Boron is classified as a metalloid is not found naturally on earth. Along with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds featuring triple bonds. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. Boron is found in borates, borax, boric acid, colemanite, kernite, and ulexite.The name Boron originates from a combination of carbon and the Arabic word buraqu meaning borax.
