Abstract

"The purpose of this investigation was to develop a samarium containing aluminosilicate glass with properties suitable for use in the treatment of rheumatoid arthritis. Microspheres made from these compositions would be neutron activated to produce radioactive Sm-153 which has beta-particle energies suitable for treating rheumatoid arthritis as well as appropriate gamma-ray emission for nuclear imaging. The properties of Sm₂O₃ · AI₂O₃ · SiO₂ glasses containing 10 to 25 mole% Sm₂O₃ were evaluated as a function of composition. The density, refractive index, thermal expansion coefficient, and microhardness increased with increasing Sm₂O₃ content. The dissolution rate in 1N HCl and deionized water at 37°C increased whereas the dissolution rate in deionized water at 70°C decreased with increasing Sm₂O₃ content. Several glasses had excellent properties suitable for radiotherapeutic applications. The composition range for the glasses best suited for these applications was (10-25) Sm₂O₃ · (20-35) Al₂O₃ · (40-70) SiO₂ (mole%)"--Abstract, page iii.
