Synthesis of Potassium Magnesium Titanate with Layered Crystal Structure from Hydrous Potassium Tetratitanate

摘要

Potassium magnesium titanate (KMT) was synthesized in single-phase by calcination at 1000 deg C for 1 h from magnesium nitrate 6-hydrate and hydrous potassium tetratitanate fiber. For comparison, mixture of potassium carbonate, magnesium nitrate 6-hydroate and titanium dioxide powders was calcined, and KMT and small amount of ann amorphous phase, which is found by TEM. Hydrous potassium tetratitanate fiber and magnesium nitrate 6-hydrate phases were found. The distance between its layers in crystal structrue was different from the soaking condition.
