in Ceramic Applications :
Wolkem’s various milled grades of Calcite are
used in Ceramic industry for Wall Tile, Floor
Tile, Sanitary ware, Glaze & Frit, High
& Low Tension Insulator applications.
- Calcite provides better bonding and green
strength in ceramic glazes.
Calcite containing CaO is the principal flux
in medium & high temperature glazes. It
reduces the viscosity and co-efficient of thermal
expansion. It promotes adherence, stability,
hardness and toughness to the glaze when used
in a proper concentration. Calcite also whitens
the glaze to the greater extent by its bleaching
action. It is used as source of lime (CaO) in
sanitary ware glazes & floor tile glazes
