Trimethylaluminum (TMA) is a precursor for Aluminum Oxide deposition and is the most popular aluminum precursor used for the production of Metal-Organic Vapor-Phase Epitaxy. Trimethylaluminum is also used as a methylation agent and is often released from sounding rockets as a tracer in studies of upper atmospheric wind patterns. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. See safety data and research below and pricing/lead time above. Trimethylaluminium is available in a wide range of ultra-high purity grades. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Aluminum (Al) atomic and molecular weight, atomic number and elemental symbolAluminum, also known as Aluminium, (atomic symbol: Al, atomic number: 13) is a Block P, Group 13, Period 3 element with an atomic weight of 26.9815386. It is the third most abundant element in the earth's crust and the most abundant metallic element.Aluminum Bohr ModelAluminum's name is derived from alumina, the mineral from which Sir Humphrey Davy attempted to refine it from in 1812. It wasn't until 1825 that Aluminum was first isolated by Hans Christian Oersted. Aluminum is a silvery gray metal that possesses many desirable characteristics. It is light, nonmagnetic and non-sparking. 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. Elemental Aluminum Although it has only 60% of the electrical conductivity 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 it imparts a variety of useful properties. Aluminum was first predicted by Antoine Lavoisierin 1787 and first isolated by Friedrich Wöhler in 1827.
