Synthesis of Potassium Titanate Whiskers by Microwave Heating
钛酸钾晶须的微波合成

A method for synthesizing potassium titanate whiskers by microwave heating is described in this paper. A series of potassium titanium whiskers (K2Ti2O5, K2Ti4O9, K2Ti6O13) with diameter in the range of microns were obtained. Potassium carbonate and hydrous titanium oxide are used as starting materials. CuO and Fe3O4 are used as heating medium in order to induce the temperature. The effect of the experimental conditions including the ratio of starting materials, heating medium and irradiating time on the structure and morphology of the products were investigated. It was proved that the growth of whisker under microwave heating could be modeled with a liquid melt inducing mechanism.
