Description

Trimethylaluminium is a highly reactive organoaluminium compound, widely recognized as a crucial precursor in advanced material synthesis and catalysis. Its primary commercial value lies in its exceptional reactivity as a methylating agent and its role in forming high-purity aluminum-containing films. This product is essential for manufacturers and research institutions in the semiconductor, polymer, and fine chemical industries, where precise control over chemical vapor deposition (CVD) and polymerization processes is required.

Application

• Semiconductor Manufacturing: As a key precursor for Metal-Organic Chemical Vapor Deposition (MOCVD) to produce high-purity aluminum nitride (AlN) and aluminum oxide (Al2O3) thin films for LEDs and electronic components.
• Polymer Catalyst: Acts as a co-catalyst in Ziegler-Natta type systems for the production of polyolefins, such as polyethylene and polypropylene.
• Organic Synthesis: Employed as a potent methylating and reducing agent in the synthesis of specialty chemicals and pharmaceutical intermediates.
• Material Science Research: Used in the development of novel aluminum-based nanomaterials, metal-organic frameworks (MOFs), and ceramic precursors.
• Rocket Propellant: Serves as a high-energy additive in advanced fuel formulations.

Quality Control

Our Trimethylaluminium is produced and handled under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the high-purity standards required for electronic and catalytic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and highly volatile nature, it must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Specific storage temperature ranges are available upon request and are dependent on the container and concentration.
