A particulate material comprises hollow or cup-shaped ceramic microspheres having a diameter in the range of from 5 to 200 microns, the microspheres being formed from a base material comprising greater than 70% by weight of yttria or another yttrium-containing compound together with one or more comp

A particulate material comprises hollow or cup-shaped ceramic microspheres having a diameter in the range of from 5 to 200 microns, the microspheres being formed from a base material comprising greater than 70% by weight of yttria or another yttrium-containing compound together with one or more compounds selected from the group consisting of alumina or another aluminium-containing compound, zirconia or another zirconium-containing compound, and silica or another silicon-containing compound. The particulate material may comprise a beta-radiation emitting radionuclide ytrrium-90, and be used in selective internal radiation therapy (SIRT) of various forms of cancer and tumors.
