摘要 |
The present invention provides a sol comprising, as a dispersoid, amorphous Zr-O-based particles having a median particle diameter D 50 of 50 to 200 nm, so as to enable control of the optimal rheology and the application characteristics of a mixture system incorporating the sol. More specifically, the present invention provides a sol comprising, as a dispersoid, amorphous compound particles containing zirconium and oxygen, the amorphous compound particles having a median diameter in a range of 50 to 200 nm. |
