Process for producing crystalline fibrous potassium titanate

摘要

A crystalline fibrous potassium titanate having the formula K2O.6TiO2 is produced by melting a mixture of a titanium component and a potassium component; quenching the molten product on a plate; removing the unreacted K2O and excess K2O from the quenched product by washing water or an acid; and heat-treating the product to improve crystallinity.
