Wollastonite is a naturally occurring calcium meta silicate mineral with the molecular formula CaSiO3. Wollastonite is unique among non-metallic industrial minerals for its combination of white colour, acicular (needle-like) crystal shape and alkaline pH.

Advantages of Wollastonite in Metallurgical application:

• Reduce nozzle blockages
• Absorbs non-metallic inclusion
• Works as natural low temperature flux,
• It absorbs alumina.
• Adds reinforcement and thermal shock resistance to metal casting plasters.
• Virtually no finishing needed for casting after removal from mould
• It is readily fusible and gives low viscosity resulting in higher flow ability. 
• Prevents re oxidation

CCMP – Continuous Casting Mold Powders

• Low aspect ratio Wollastonite grades are used up to 40%.
• Wollastonite Provides – ready fusibility, good insulating qualities, & low viscosity fluxes.
• During continuous casting high fluidity of molten, wollastonite helps to minimize breakouts & reduce mold wear by lowering the overall viscosity.
• The low thermal conductivity & low bulk density of wollastonite in unmeted layers provides a uniform insulating cover.

Recommended Grades

• Kemolit H-2
• Kemolit H-3
• Kemolit KW-2
