Abstract
The invention relates to a liquidoid in situ method for preparing a nano zinc borate crystal whisker under normal pressure and low temperature, which comprises following steps: 50 milliliter of a borax solution with the concentration of 0.05 to 0.2 mol per liter is placed into a three-necked bottle, an aqueous solution of a cation surfactant is added and agitated evenly, 10 milliliter of a zinc salt with the concentration of 1 to 2 mol per liter is then added, temperature is heated until 50 to 90 DEG C, and crystallization is implemented by 7 to 10 hours of agitation at constant temperature; a white deposition that is obtained is filtered, washed and dried at the temperature of 50 to 90 DEG C, thus obtaining powder of the nano zinc borate crystal whisker with the diameter of 20 nm to 40 nm, the length of 500 nm to 1 um and the slenderness ratio of 25 to 50. The liquidoid in situ method for preparing the nano zinc borate crystal whisker is characterized in that the method has simple preparation techniques, does not use a fluxing agent and a high-pressure reaction kettle, does not need high-temperature calcinations, does not generate pollution, and has low cost, high productivity and higher economical and social values.
