l Diethylzinc for thin film solar cells Nouryon
We are Nouryon, your partner in essential chemistry for a sustainable future
A long history
We have a long history in metal alkyls, starting with large-scale production of aluminum alkyls in 1959. Today, we're one of the world's top producers with a broad range of metal alkyls, including aluminum, magnesium, boron and zinc alkyls. Our ultra-high purity semi-con- ductor-grade product range includes gallium-, indium-, aluminum-, zinc- and magnesium-based MO-sources. We are the only fully integrated high purity metalorganics supplier serving the semiconductor industry, producing our own trimethyl aluminum, a key raw material for these products. Nouryon also plays a role in the fast-growing solar cell market. We have developed new technology for the production of high purity diethyl zinc, which is used by thin film solar cell manufacturers to create the all-important TCO layer. It is our contribution to solar energy, for the benefit of our planet. At Nouryon we look beyond horizons. We believe that what is good for you today is not necessarily good for you tomorrow. We are committed to the success of our customers. That’s why we continually invest in high-quality standards, innovation, safety, active technical support and better distribution systems.
Nouryon pioneered the large-scale production of diethyl zinc (DEZn) and has been producing commercial quantities in La Porte (Texas, USA) since the 1960s. Main applications are as ZnO precursor for the TCO layer in thin film solar cells and in pharmaceutical synthesis. Our product grade specifical- ly aimed to serve the needs of the solar cell industry is called DEZn TCO. Nouryon has acquired Zhejiang Friend Chemical Co. (Friend), the largest Chinese producer of triethyl aluminum (TEAI) – a metal alkyl used in the produc- tion of high-volume polymers, such as polypropylene and polyethylene. The acquisition will substantially raise our organization’s global TEAI produc- tion and strengthen our position as a leading global producer of TEAI. The deal also makes us the only truly global producer of metal alkyls. All our sites are ISO 9001 and ISO 14001 certified to ensure the highest product quality and strict compliance with environmental regulations. Additionally, La Porte is an OSHA VPP Star site and both Rotterdam and Paulinia have achieved OHSAS 18001 certification. Our sites in the Americas have achieved RC 14001 certification as well. We supply a broad range of metal alkyls from our La Porte (Tx - USA) and Rotterdam (the Netherlands) sites, as well as from smaller facilities in China, India and Brazil. Our global distribution network allows us to deliver products to you anywhere in the world. That’s how we ensure security of supply and easy access to quality products wherever you are.
Nouryon uses leading edge processes, purification and transfilling techniques that ensure the repeatable and consistent delivery of the highest purity DEZn TCO in each cylinder that we supply. We apply state of the art techniques such as ICP-AES for trace metal analysis to meet customer's demands. Product specifications are provided on our Product Data Sheet (PDS), which is available on nouryon.com/hpmo
We maintain a fleet of cylinders and portable tanks designed for the shipment of DEZn TCO. Shipping containers are designed and constructed to meet all national and international transport regulations and are tested periodically, in accordance with the appropriate regulations. Containers are fabricated from carbon steel and are equipped with dip tubes for top discharge. Valves are equipped with standard VCR connections.
* Exact volume of an ISO tank container depends on the model
Nouryon’s success in safely handling DEZn is due to our long-term commitment to safety. Knowledge of proper handling techniques, carefully designed facilities and thorough training of personnel can overcome the hazards. Personnel who understand and pay proper attention will be able to handle metal alkyls confidently and safely.
Safety and Handling
DEZn ignites upon exposure to air and reacts violently with water. DEZn must be handled under a dry, inert atmo- sphere, e.g. nitrogen or argon. DEZn may undergo exothermic decomposi- tion with evolution of flammable gas if stored above 70°C (158°F). The decomposition may become self-accelerating and UNCONTROLLA- BLE and may result in an explosion if heated above 120°C (248°F). 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. Products of complete combustion of DEZn are z`inc oxide, carbon dioxide and water. DEZn causes severe burns to the skin and eyes. It is imperative that proper personal protective equipment be wom when handling DEZn.
Storage
DEZn is stable when stored under a dry, inert atmosphere and away from heat. DEZn may undergo violent exothermic decomposition with flammable gas evolution if stored at temperatures above 70°C  (158°F).
Safety Services
Nouryon is recognized as a global leader in metal alkyl safety. We always place safety as our top priority. Sharing our experience in safety is one of the most important resources we offer. Through our safety programs we can provide expert advice on the handling of these materials including: • classroom review of safety and handling of metal alkyls • consultation of metal alkyl facility design • demonstrations on the safe use, handling and control of metal alkyls • on-site assistance and advice regarding procedures As such, we routinely advise our customers on the development of systems which deliver DEZn from our bulk containers to their production tools and the safety procedures that should be employed in these produc- tion processes. Please contact us if you are interested in such services.
Your global Nouryon HPMO team is here to serve you. For more information, please contact your sales manager or regional Nouryon sales office.
