Sodium silicate and PAM were selected as dispersants, laser diffraction-based particle size analyzer and settlement experimentation were used to evaluate dispersion and stability of nano-particles.

本实验选择了九水合硅酸钠和聚丙烯酰胺作为分散剂，并通过激光粒度分析仪和沉降实验对纳米颗粒的分散稳定性进行评价。

The inorganic material is nano dispersed suspension formed by co-precipitation hydrothermal reaction and surface treatment reaction of laminated silicate, nitrate or the both.

无机材料由层状硅酸盐、硝酸盐或它们经共沉淀水热反应与表面处理反应形成纳米分散悬浮液。
