Diethylzinc - DEZn

AkzoNobel offers the highest purity diethylzinc under the product name of DEZn SSG (Select Semiconductor Grade). DEZn SSG is a zinc precursor for the deposition of compound semiconductors. Compound semiconductors are used in applications such as light emitting diodes, laser diodes, high performance transistors and high efficiency solar cells.

DEZn TCO for thin film solar cells

Under the name of DEZn TCO we also a product grade specifically aimed to serve the needs of the solar cell industry. DEZn TCO is used to create the TCO (transparent conductive oxide) layer in thin film solar cells and other thin film processes.

Please refer to the Product Data Sheet for DEZn SSG or download the DEZn TCO brochure for more information.

Diethylzinc is stable when stored under a dry, inert atmosphere and away from heat. Diethylzinc may undergo violent exothermic decomposition with flammable gas evolution if stored at temperatures above 70°C (158°F).  

Packaging and transport
DEZn SSG containers are made of stainless steel with an electropolished internal finish and are equipped with dip tube for top discharge and diaphragm valves. The diaphragm valves are equipped with metal gasket face seal connections such as Swagelock® VCR®.
DEZn TCO containers are fabricated from carbon steel and are equipped with dip tubes for top discharge. Valves are equipped with with standards VCR connections. 

Safety and handling 
Diethylzinc ignites upon exposure to air and reacts violently with water. Water must be scrupulously removed from process equipment prior to putting it into metal alkyls service. Failure to do so may result in an explosion. Diethylzinc may undergo exothermic decomposition with evolution of flammable gas above 70°C. The decomposition may become self-accelerating and uncontrollable and may result in a violent runaway reaction if heated above 120°C. Products of complete combustion of diethylzinc are zinc oxide, carbon dioxide and water. Diethylzinc causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be worn when handling DEZn SSG. 

Please refer to the Material Safety Data Sheets (MSDS) for DEZn SSG and DEZn TCO further information on the safe storage, use and handling of diethylzinc. This information should be thoroughly reviewed prior to acceptance of our product.
