 Isonics Receives First Shipment of Commercially Produced Silicon-28 Trichlorosilane
 
 GOLDEN, CO August 16, 2001– Isonics Corporation (NasdaqSC: ISON /ISONW) (OTCBB: ISONL /ISONZ) and (Frankfurt: IO9) a leader in the development of isotopically pure silicon-28 wafers for semiconductor device manufacture announced that it has received the first commercially produced Si-28 Trichlorosilane (Si-28 TCS) from its Russian supplier.  Isonics will characterize the material to establish its conformance with Isonics’ and industry specifications.
 
 Dr. Stephen Burden, Isonics’ Vice President of semiconductor materials commented, “We are quite encouraged in receiving this material from our trusted isotope supplier.  We will perform rigorous evaluations at a number of independent laboratories.  Once we have qualified this new product form, we plan to place an order for 200 kg to replace that Si-28 which was supposed to have been delivered by Eagle-Picher, and plan to use it to produce single crystal bulk wafers for customer evaluations.
 
 “Trichlorosilane is a different chemical form of silicon-28 than we had previously received from this supplier and which we were expecting to obtain from Eagle-Picher.  This form will require much less processing to turn it into a useable product and should be more economical in the long-run.  We are informed that quantities of silicon-28 will be limited only by our willingness to place purchase orders.”
 
 Isonics is a world leader in isotopically engineered materials and produces isotopically pure silicon-28 chemicals and wafers for the semiconductor industry.  Isonics also markets and sells stable isotopes for the health care industry such as carbon-13 for diagnostic breath tests and drug design, and oxygen-18 for positron emission tomography (PET) imaging.  Stable isotopes can be thought of as ultra pure materials. For additional information visit www.isonics.com.
