METHOD FOR PRODUCING MAGNESIUM POTASSIUM TITANATE AND LITHIUM POTASSIUM TITANATE

摘要

PROBLEM TO BE SOLVED: To obtain a uniform plate-like titanate without using a flux for which wide range of titanium sources including one with low purity can be used as the raw material.;SOLUTION: This method for producing magnesium potassium titanate expressed by the formula: K_0.8Mg_0.4Ti_1.6O₄ or lithium potassium titanate expressed by the formula: K_0.8Li_0.27Ti_1.73O₄ comprises the steps of mixing (1) a titanium source, (2) a potassium source and (3) a magnesium source or a lithium source, subjecting the mixture to grinding treatment in a vibration mill, and firing at a temperature in the range of 500 to 1,150°C.;COPYRIGHT: (C)2004,JPO
