Abstract of the Disclosure A chemical vapor deposition process for making glass-surfaced microcarriers, and the resulting product, in which hollow spherical micro-sized shells of glass or ceramic composition replaced within a fluidized bed coater, and separate preheated reaction gasses are directed into the coater bed. The shell precursors have a preferred starting density of not more than the predetermined desired final density in the range of 1.01 to 1.2 g/cc, and have a diameter in the range of 5 to 500 µm, preferably 105 to 150 µm. The thickness of the silicate glass coating is preferably in the range of 11 to 16 µm. An alternative embodiment employs solid precursor beads of polyphenylene oxide.
