A comparison study of three fluxing agents in promoting …
Fluxing agents can greatly decreased the specific surface, pore volume and pore diameter of fired brick. For example, after adding 30 wt% of WGP, Na and K-feldspar, the specific surface area of fired bricks decreased from 4.8 m 2 /g to 1.4 m 2 /g, 1.9 m 2 /g and 1.8 m 2 /g, and the pore volume decreased from 0.196 m 3 /g to 0.0073 m 3 /g, 0. ...
