PRODUCTION OF POTASSIUM TITANATE ALUMINATE WHISKER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing potassium titanate aluminate whisker having a fine shape. ;SOLUTION: This method for producing potassium titanate aluminate whisker comprises heating at least one titanium supplying component selected from a particulate or fibrous titanium supplying component of the formula TiO₂.nH₂O ((n) is a real number of 0-8) and at least one aluminum supplying component selected from aluminum hydroxide, aluminum oxide hydrate, inorganic acid salt of aluminum and an alkali metal aluminate in the presence of a melting agent at 900-1,300°C, further cooling and, reacting the components and growing potassium titanate. The melting agent is at least one selected from the group consisting of potassium chloride, potassium sulfate and potassium bromide.;COPYRIGHT: (C)1997,JPO
