From the Latin word "alumen" meaning "alum". The ancient Greeks and Romans used alum in medicine as an astringent, and in dyeing processes.
Atomic Number = 13, Atomic Mass = 26.98, 13 protons, 13 electrons, 14 neutrons.
First isolated by Hans Christian Oersted of Denmark in1825.
Most common use:
- cans and foils
- kitchen utensils
- Residential house siding
- Industrial applications where a strong, light, easily material is needed
- Wire for electricity, although its electrical conductivity is only about 60% that of copper per area of cross section, it is used in electrical transmission lines because of its lightness and price
Alloys are of vital importance in the construction of modern aircraft and rockets
Aluminum silicate is a mineral formed by a mixture of aluminum, silica and oxygen and hence the formula Al2 (SiO3)3. It has low bulk density and a super white color.
Some of the properties of aluminium Silicate are:
Lighter in weight
Super white in color
High degree of brightness
Low plasticity
Ease of dispersion
Good oil absorption.
