为进一步探讨高性能Mg CO3·3H2O晶须制备的影响因素,采用低温液相法,合成出Mg CO3·3H2O晶须产品.主要研究反应时间对Mg CO3·3H2O晶须产品的影响.研究结果表明:反应时间短,造成Mg CO3·3H2O晶须产品不能充分生长发育,晶须产品长度短、长径比小;反应时间过长,导致已经生成的晶须产品发生碰撞,晶须长径比进一步变短.适宜的反应时间为60 min.研究结论将对高长径比晶须产品的合成具有一定的参考价值.
In order to further investigate the influencing factors on the preparation of high-performance MgCO 3 · 3H 2 O whiskers, MgCO 3 · 3H 2 O whiskers were synthesized by low temperature liquid-phase method, and the effects of reaction time on MgCO 3 · 3H 2 O whiskers were studied. : The reaction time is short, resulting in insufficient growth and development of MgCO3 · 3H2O whiskers, short whisker length and small aspect ratio. The reaction time is too long, resulting in the collision of whisker products that have been generated. The whisker aspect ratio further Shortened.The suitable reaction time is 60 min.The conclusion of the study will be of certain reference value for the synthesis of high aspect ratio whiskers.
