Firstly, the specific surface area of nano-coated particle is much larger than that of ordinary wollastonite, and the edges formed in comminuting is passivated, which made the slippy crystal surface coarsened. At the same time, the color of nano-coated particle became whiter, which fit for light ware. Secondly, if the coated wollastonite hasn't been modified by coupling agent, the toughness of PP/ wollastonite composite couldn't be improved.

在硅灰石表面包覆上纳米级SiO2小颗粒对硅灰石的应用特性有重要影响：①纳米包覆粒子填料的比表面积比普通硅灰石大，纳米级SiO2小颗粒钝化了由于机械力粉碎造成的硅灰石的棱角，使其平滑的晶体解理面变得粗糙，同时硅灰石粉体白度增大，可应用于浅色制品。
