不同形貌CaCO_3微粉的制备

The preparation of various shapes of calcium carbonare

在不同条件下 ,用不同的方法 ,分别制备了无定形体、立方晶体、针状晶体、纳米级粉体和表面包覆改性的 5种不同形貌的 Ca CO3微粉。用 SEM详细观察了它们各自的形貌 ,讨论了不同晶型 Ca CO3微粉的制备原理、方法。

In this paper,various shapes of calcium carbonare were prepared with varying methods and characterized by SEM The crystalline states of calcium carbon are include:amorphous,cubic crystal,acicular crystal,nanocrystalline and surface tractment clad of nanocrystalline This study introduces the basic priniple and the preparative method of different shapes of CaCO 3.Various factors for the controlling of particle size were discussed.
