crystalline particle

Eucommia ulmoides gum ( guttapercha or balata) is a crystalline particle existing in the bark and leaf of Duzhong tree ( Eucommia ulmoides Oliv), and to extract E.

在杜仲树中杜仲胶以晶体微粒的形式存在，必需用溶剂提取或机械破坏植物组织来获取。

The results showed that both the crystalline size and particle size increased with increasing calcination temperature.

检测结果表明，粉体的晶粒度和颗粒度都随煅烧温度的增加而增大。

It shows that the doped samples synthesized by this process have good crystalline and homogeneous particle size distribution.

该工艺制备的掺杂样品结晶性好，产品粒径均匀分布。

Effects of Post-treatment Method on Crystalline Type, Particle Size, Surface Binding State of Nanometer-size TiO_2

后处理方法对纳米TiO2晶型、粒度与表面结合态的影响

A stable nanometered TiO_2 colloids were prepared from the hydrolysis of titanyl organic compounds by controlling the reaction conditions. The X-ray diffraction and scan electro microscopy ( SEM) revealed that the colloidal TiO_2 was in an anatase crystalline particle form with a diameter of 12 nm.
