纳米碳酸钙是指尺寸在纳米数量级(1～100nm)的碳酸钙颗粒,是20世纪80年代发展起来的一种新型超细固体材料。由于纳米碳酸钙粒子的超细化,其晶体结构和表面电子结构发生了变化,从晶型上分为纺锤型、链状、立方型、针型、球型等,产生了普 Nanocrystalline calcium carbonate refers to the size of nano-orders of magnitude (1 ~ 100nm) of calcium carbonate particles is the development of the 1980s a new type of ultrafine solid material. As the superfine nano-calcium carbonate particles, the crystal structure and surface electronic structure has changed from the crystal form is divided into spindle, chain, cube, needle, ball, etc., resulting in general
