Descrição geral

Trimethylaluminum (TMA) is the most reactive and volatile among all organoaluminium compounds. It is extremely pyrophoric. It acts as a highly reactive reducing and alkylating agent.

Aplicação

TMA is used in a Ziegler Natta catalyst for polymerization and hydrogenation. TMA is mainly used for the production of methylaluminoxane, such as metalorganic chemical vapor deposition (MOCVD) of:
  • Al2O3 using TMA and O2 precursors.
  • Al4C3 layers have been grown on Al2O3 (0001) using TMA and methane as source materials for aluminum and carbon.

Embalagem
