• Improved production rates
• Provides less denting
• Provides less grazing
• Reduces shrinkage
• Increases strength
• Reduces surface defects
• Low sintering temperature
• Improves glaze strength
• Improves green strength
• Improves impact and dimensional stability
• Reduces moisture and thermal expansion

• Provides a matt finish in low fired glazes
• Improves product quality
• Aid faster drying which in turn result in lowering of energy costs

Calcite 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
 

Talc in Ceramic Applications:

Wolkem’s talc is used in wall tile body, floor tile body, glazes

• It helps control shrinkage
• It acts as a source of magnesia.
