Boron Silicide Powder
Boron (atomic symbol: B, atomic number: 5) is a blocking element P, Group 13, Period 2 with an atomic weight 10.81. The number of electrons in each of the boron shells is 2, 3 and its electronic configuration is [He] 2s2 2p1. The boron atom has a radius of 90 μm and a Van der Waals radius of 192 μm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808. It was also isolated by Humphry Davy, also in 1808. Boron is classified as a non-naturally occurring metalloid on earth. Elemental boron Along with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds with triple bonds. The boron has an energy band from 1.50 to 1.56 eV, which is higher than that of silicon or germanium. Boron is found in borates, borax, boric acid, colemanite, kernite and ulexite. The name boron comes from a combination of carbon and the Arabic word buraqu which means borax.
Silicon (atomic symbol: If, atomic number: 14) is a blocking element P, Group 14, Period 3 with an atomic weight of 28.085. Silicon molecule BohrEl number of electrons in each of the silicon housings is 2, 8, 4 and configuration is electronic [Ne] 3S2 3P2. The silicon atom has a radius of 111 μm and a Van der Waals radius of 210 μm. Silicon was first discovered and isolated by Jons Jacob Berzelius in 1823. Silicon is 25.7% of the earth’s crust, by weight, and is the second most abundant element, surpassed only by oxygen. The metalloid is rarely found in the form of pure crystal and is usually produced from ferro-silicon ferrosilicon. SiliconSilica elementary (or silicon dioxide), like sand, is a main ingredient of glass, one of the most economical materials with excellent mechanical and electrical, optical and thermal properties. The ultra high purity silicon can be doped with boron, gallium, phosphorus or arsenic to produce silicon for use in transistors, solar cells, rectifiers and other solid state devices that are widely used in the electronics industry. The Latin word silex means flint or hard stone.
