TETRAKIS(DIMETHYLAMIDO)HAFNIUM(IV),

Description:

Tetrakis(dimethylamido)hafnium(IV) is an organometallic compound with the formula Hf(N(CH₃)₂)₄. It is characterized by its coordination of four dimethylamido ligands to a central hafnium atom, which is in the +4 oxidation state. This compound is typically a colorless to light yellow liquid or solid, depending on its form and purity. It is known for its volatility and is often used as a precursor in chemical vapor deposition (CVD) processes for hafnium oxide thin films, which are important in semiconductor manufacturing and other advanced materials applications. Tetrakis(dimethylamido)hafnium(IV) is sensitive to moisture and air, requiring careful handling under inert conditions to prevent hydrolysis and oxidation. Its thermal stability allows it to decompose at elevated temperatures, releasing hafnium and nitrogen-containing byproducts. Due to its organometallic nature, it exhibits unique reactivity and properties compared to traditional hafnium compounds, making it valuable in materials science and nanotechnology.

Tetrakis(dimethylamino)hafnium

Controlled Product

CAS: 19782-68-4

Tetrakis(dimethylamino)hafnium is a reactive metal oxide that can be used in the production of high-performance transparent electrodes. It reacts with water vapor to produce oxygen gas and hydrogen gas. This reaction is used to remove water vapor from the air and generate hydrogen gas, which is then collected for use as fuel. Tetrakis(dimethylamino)hafnium has a high resistance to corrosion by water vapor, making it suitable for use in environments where other metals would corrode quickly. It also has low thermal conductivity and a wide bandgap, making it suitable for use in electronics such as solar cells.
