Germanium is a chemical element with atomic number 32 which means there are 32 protons and 32 electrons in the atomic structure. The chemical symbol for Germanium is Ge . Germanium is a lustrous, hard, grayishwhite metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.
The very best of these images are collected in a Photographic Periodic Table Poster available in many sizes from place mats to classroom size. Some of these samples are of the pure element, others are of common (or uncommon) applications or minerals containing the element.
Sep 10, 2008· Titanium (Ti) can be produced by the reaction of metallic sodium (Na) with titanium tetrachloride vapor (TiCl4). The byproduct of this reaction is sodium chloride (NaCl). Calculate the amount of titanium produced (in kg) when a . asked by Basim on November 17, 2012; Science
Germanium is extracted from germanium bearing zinc ores or from certain coal ores, collecting the flue dusts after the burning process. It can occasionally be found in copper ores. We refine germanium at our facility in the USA.

Germanium gets wide applications in optical fibre communication, nightvision device, thermal imager, oil catalyst, solar cells and so on. It is available in forms as powder, shots, cubes and so on. Vanadium is with melting point 3380℃, so it forms stable carbide compound(V4C3) with C elements in steels.
Germanium oxide (GeO2) glass fibers show high transmission for infrared light with wavelengths shorter than μm. GeO2 glass fibers have advantages, in that they are fabricated by the same process as silica glass fibers (Takahashi and Sugimoto, 1984a) and are already on the market as an optical fiber for Er:YAG lasers with a wavelength of μm.
