Abstract
Fibrous potassium titanate comprises heating to a temperature of 950.degree. C. to 1300.degree. C. potassium titanate of the general formula K.sub.2 O.nTiO.sub.2 in which n is from 3 to 5, or a mixture of materials from which potassium titanate is formed, to form is manufactured by decomposition a solid phase of potassium hexatitanate and a liquid phase of potassium titanate of the general formula K.sub.2 O.nTiO.sub.2 (2.ltoreq.n.ltoreq.3), cooling said potassium hexatitanate and potassium titanate slowly to a temperature of 900.degree. C. to 950.degree. C., and controlling the rate of said cooling to cause a bonding of said potassium hexatitanate and said potassium titanate to form a solid phase of potassium tetratitanate fibers, whereby potassium titanate according to said general formula in which n is from 4 to 6 is caused to grow in single crystal form.
