Silica Fume for Concrete and Refractory Material

Silica fume for polished tile: This microsilica is commonly used in the manufacture of polished tiles to increase their resistance to corrosion and other properties.

silica fume for ceramics, is used in ceramic production to reduce firing temperatures and shorten firing cycles. It constitutes the Si-Al-Ca low eutectic system in silicate ceramics, and the generated material phase is mainly calcium feldspar, which achieves sintering at a lower temperature. Wollastonite's needle and columnar crystalline form provides a channel for the rapid escape of moisture in the blank, accelerating the drying rate, shortening the drying cycle and improving production efficiency.

In addition, wollastonite reduces sintering shrinkage and product defects, ensures product dimensional stability, and prevents deformation of the ceramic body. It itself does not contain water and carbonate and other volatile components, the firing process does not produce gas, reducing the possibility of ceramic firing body to produce porosity defects, significantly improving the quality of ceramics.
