ABSTRACT:
The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies. The addition of refined wollastonite to sanitaryware bodies exhibited improved resistance to propagation of cracks, reduced drying and firing shrinkage, fluxing activity, an HF release inhibition upon firing. Reduced shrinkage and increased permeability improves the resistance to cracking during rapid drying and allows faster time schedules to be employed.
