| Abstract: | The aragonite CaCO3 whiskers are prepared by dropping the deliquate solution of CaCl2 and Na2CO3 into distilled water at the same time without any crystallize control agent, they want ratio of length and diameter which are smooth and uniform. The optimized processing parameters are that the value of pH is 8, the concentration of CaCl2/Na2CO3 solution is 0.025mol/L, the velocity of dropping is 1.20ml/min, the diameter of dropper is 3mm, the agitation rate is 500r/min. |
