Sep 01, 2013 Xray attenuating hand cream shields interventionalists By Eric Barnes, staff writer August 15, 2013 A new bismuthoxidebased hand cream recently approved by the U.S. Food and Drug Administration FDA might free interventional radiologists to focus more on their patients and worry less about radiation exposure to their own hands.
Mechanochemical synthesis was performed in a planetary ball mill in air atmosphere. Bismuth titanate ceramics was obtained by sintering at 1000 oC. The formation of Bi4Ti3O12 in the sintered samples was confirmed by Xray diffraction analysis. Scanning electron microscopy, SEM, was used to study the particle size and powder morphology.
Mechanochemical Activation Assisted Synthesis of Bismuth BIT ceramics were determined by Xray diffraction and EDS analysis. After milling for analysis of BIT powder, treated for different milling times, showed a rapid increase of Bi4Ti3O12 phase formation after 1 h of milling time. All peaks appeared to be very broad as a
