Corundum Gem Guide and Properties Chart

Corundum is a mineral species best known for its two popular gemstone varieties sapphire and ruby All colors of corundum except red are known as sapphire The term sapphire when used without any modifiers refers to only the blue variety of corundum Red stones are known as ruby Material that are not gemstones are simply known by the name

Corundum RUSAL

Corundum products RUSAL is one of the world’s major producers of white fused alumina It is produced by fusing pure alumina in electric arc furnaces at the Boksitogorsk Alumina Refinery Due to its ultrahigh strength white fused alumina is used for producing abrasive tools and because of its resistance to high temperatures and low thermal

Lattice thermal conductivity of MgO at conditions of Earth

2010222 Despite its importance thermal conductivity remains as one of the least constrained physical properties of minerals especially at lowermantle pressures P and temperatures T 23–135 GPa and approximately 1900–4000 K 9–12Experimental data at deep mantle conditions are scarce due to the technical difficulty of measuring thermal conductivity at these
