"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.
