Arsenic - SAMaterials

Arsenic is a chemical element with the syol As, and atomic nuer 33. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition).

Silicon - Wikipedia

Silicon carbide is rapidly attacked by chlorine gas, which forms SiCl 4 and carbon at 100 C and SiCl 4 and CCl 4 at 1000 C. It is mostly used as an abrasive and a refractory material, as it is chemically stable and very strong, and it fractures to form a very sharp cutting edge.
