Zirconia White Micro Silica Fume Power / Granular With Large Surface Area
Zirconia White Microsilica Fume Powder for Refractories/Shotcrete/Concrete/Cement/Motar Industries
1. White Micro Silica Fume Introduction
White micro silica fume (powdery) is a very rare micro silicon powder. It is very strict on the raw material and production process. Its production is very small, and it can be used in superfine fillers with high whiteness requirements, such as grout, sealant, repair agent and so on.
