Notes
Vansil is an exceptionally white calcium metasilicate (CaSiO3) mineral with low oil absorption or binder demand. It is useful as a ceramic flux and mineral filler. It is used in ceramic wall and floor tile, in glazes and in frits for glazes and enamels. It also finds use in glaze and body stains, in grain bonding for vitrified grinding wheels, in electrical insulators and as an auxiliary flux.
Different grades of the material vary in particle size.
Density Mg/m3 2.9
pH at 10% solids 9.8
Abrasiveness (Einlehner M/M2 loss, 174,000 revolutions) 400-500
-325mesh -10 -5 -2.5
Vansil W10 97.3 33 20 10
Vansil W20 98.0 53 34 16
Vansil W30 99.0 75 37 18
