An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

After fired at 1600℃, with the increase of zircon addition the bulk density of the samples increases while apparent porosity decreases. When zircon addition is 4%, the strength is the best, and the photomicrograph of the sample exhibits a densely packed microstructure, with larger and better developed grains of periclase and spinel. Meanwhile, the direct bonding of solid phases is reinforced.
