Process for the production of fibrous potassium titanate

摘要

In the production of fibrous potassium titanate by the hydrothermal reaction of a mixture of a tetravalent titanium compound and a potassium compound in an aqueous alkaline solution at a high temperature under a high pressure, the hydrothermal reaction is carried out in the presence of at least one member selected from the group consisting of compounds of titanium having less than four valencies, metallic titanium and mixtures thereof, while removing a part of water formed during the reaction from the reaction system.
