Aluminum Potassium Sulfate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Aluminum is a Block P, Group 13, Period 3 element. The electronic configuration is [Ne] 3s2 3p1. In its elemental form aluminum's CAS number is 7429-90-5. The aluminum atom has a radius of 143.2.pm and it's Van der Waals radius is 200.pm. Aluminum is a silvery-white metal that possesses many desirable characteristics. It is light, nonmagnetic and nonsparking. It stands second among metals in the scale of malleability, and sixth in ductility. It is extensively used in many industrial applications where a strong, light, easily constructed material is needed. Although it's electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat.
