Morphology control of calcium carbonate

Morphology control of calcium carbonate

Nano calcium carbonate refers to the size of calcium carbonate in the order of nanometer. Due to the different preparation methods and surface modification methods, it can have a variety of morphology, such as spindle, needle, spherical, cubic, chain, etc. The different morphology has different nano characteristics.  

 

 

 

Because of nanometer calcium carbonate particles, ultrafine its crystal structure and surface electronic structure changed, the ordinary calcium carbonate does not have the small size effect, surface and interface effect, quantum size effect, macroscopic quantum tunneling effect, in magnetic, catalyst, and heat resistance and melting point has superior performance than conventional materials.
