Potassium magnesium titanate (KMT) was synthesized in single-phase by calcination at 1000℃ for 1 h from magnesium nitrate 6-hydrate and hydrous potassium tetratitanate fiber. For comparison, mixture of potassium carbonate, magnesium nitrate 6-hydrate and titanium dioxide powders was calcined, and KMT and small amount of an amorphous phase, which is found by TEM. Hydrous potassium tetratitanate fiber and magnesium nitrate 6-hydrate were heated at 1000℃ for 1 h to obtain KMT short fibers containing small amount of magnesium oxide as a by-product. The fibers were 10-80 μm long and 1-3 μm in diameter. The fibers were soaked in water and their hydrate phases were found. The distance between its layers in crystal structure was different from the soaking condition.
