Rhenium glass microspheres composed of metallic rhenium particles dispersed within a magnesium aluminoborate glass matrix were produced by sintering ReO2 powder and glass frit at 1050 deg C. The in vitro chemical durability of radioactive and nonradioactive microspheres was determined from chemical corrosion tests on microspheres immersed in phosphate-buffered saline (PBS) solution at 37 deg C. The dosimetric properties of these microspheres were also calculated. The Rhenium glass microspheres are chemically durable in body fluids and released
