PRODUCT INTRODUCTION
description
Trimethylaluminium (TMA) is an organoaluminium compound. It is used in the production of methylaluminoxane and Tebbe's reagent, as well as in semiconductor fabrication to grow thin film, high-k dielectrics. Aluminum is the most abundant metal in the earth's crust and is always found combined with other elements such as oxygen, silicon, and fluorine. (L739, L740, L782)
