Dense polycrystalline barium magnesium titanate in a tubular geometry has been produced directly from the melt by the edge defined film-fed growth. Chemical analysis combined with X-ray, metallographic, and density data, are sufficient to determine closely the composition of the barium magnesium titanate phase. The volume fraction of the rutile phase was determined and because no weight is gained and the microstructure does not change, this volume fraction must remain nearby constant even after annealing in O2. The chemical formula for the barium magnesium titanate phase may be written as Ba2-xMg2-yTi8-zO16 where x, y and z are only approximately unity and not necessarily equal
