Potassium titanate whisker using for brake lining material in automotive brake systems since the asbestos on toxic substances. PTW are a major role in preventing light-hazardous materials to asbestos dust generated during automobile braking and improves the wear resistance more than twice the asbestos brake lining. K2Ti6O13 whisker have been synthesized by a flux method. The average size and distribution of the synthesized K2Ti6O13 whisker can be controlled by mole ratio of potassium precursor, reaction temperature and time. The average size of the synthesized K2Ti6O13 whisker was about in the size range of 500nm to 1um and diameter range of 20 to 50nm. The size distribution of the synthesized K2Ti6O13 whisker was uniform. The effect of synthesis parameters, such as the molar ratio of potassium precursor, reaction temperature and time, are discussed.
