ABSTRACT:
A novel noncrystalline fibrous potassium titanate and a process for preparing said titanate fiber by calcination of a mixture of potassium compound(s) and titanium compound(s) at a temperature of from 800.degree. C. to the melting point of the mixture to obtain whiskers formed on the surface thereof; and an improved process for preparing fibrous potassium hexatitanate which comprises calcining hydrated fibrous potassium titanate at a temperature of 500.degree. to 900.degree. C. or which comprises kneading a mixture of potassium compound(s) and titanium compound(s), and calcining the thus kneaded mixture at a temperature of 1150.degree. to 1300.degree. C. to obtain fibers from the inside of the bulk of the calcined mixture are described.
