Trace element measurements in high purity synthetic Al2O3 via neutron activation



Trace element measurements in high purity synthetic Al2O3 via neutron activation



Applied Radiation and Isotopes 70(7): 1203-1205



We present results from our use of thermal and fast neutron activation for the determination of trace elements in Al2O3 fabricated via the heat exchanger method (HEM™). This material has applications in microwave oscillators and gravity-wave detection. Typical concentrations obtained from these measurements show the presence of Cr (5 ppb+20%), Ti (300 ppb±9.7%), Mo (1500 ppb±15%) and Sc (3 ppb±6.7%). Details of the experiments and interpretations are given.
