Discussion the reason about water extract of spherical ultrafine Silica powder to show Acidic

WANG Lihua LI Jiande CHENG Shangxu ZHOU Wenmei LIANG Haixia GAO Lirong LIU Yongfang (National Center of Quality Supervision and Inspection on Deep Processing Silicon Products Lianyungang 222000)  
Spherical ultrafine silica powder,was extracted by water,Trace analysis of metallic impurity was carried out by ICP-AES,and Surface morphology analysis was carried out by SEM,with the microzone element content analysis by EDS,The results show that the particle size of the tested sample is nanometer grade mostly,during silica powder spheroidizing.the nanometer-grade powder with large specific surface area has stronger adsorption of carbon dioxide than micrometer-grade powder.after the spherical ultrafine silica powder was extracted, Carbon dioxide was dissolved in water,and the solution showed acidic,Which is the reason.
