Aluminum (gen) : symbol Al, most abundant metallic element in the earth's crust. The atomic number of aluminum is 13; the atomic weight is 26.9815. Aluminum is a lightweight, silvery metal. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists corrosion. Aluminum is never found as alone but commonly occurs as aluminum silicate or as a silicate of aluminum mixed with other metals. Expensive to refine, these silicates are not useful ores. Bauxite, an impure hydrated aluminum oxide, is the commercial source of aluminum and its compounds. A low-cost technique dating from the 1880s is still the major method of production. Aluminum weighs less than one-third as much as steel. Its high strength-to-weight ratio makes aluminum useful in many applications
Germicide (water) (water) : A substance formulated to kill germs or microorganisms. The germicidal properties of chlorine make it an effective disinfectant.
