VANSIL^® W-20

VANSIL^® W-20 Wollastonite is used in ceramic wall and floor tile bodies; in glazes (matt and high gloss) and in frits for glazes and enamels; and in ceramic pigments and body stains. In refractory and electrical applications, VANSIL W-20 wollastonite is used in bonds for vitrified grinding wheels, in electrical insulators, and as an auxiliary flux. Established benefits include: improved green strength, minimal gassing, improved melt control, improved thermal expansion control, improved impact resistance, reduced drying time, improved surface appearance in glazes, improved transparency in glazes, prevention of bubbles when formulating leadless glazes. VANSIL W-20 is a coarser grade of wollastonite than VANSIL W-30.
